Linq Query Syntax Return Type is not IGrouping

$
0
0

While testing linq queries I stumbled on an interesting error:

QuerySyntaxVB

When using the group by clause using query syntax the return type is not “Ienumberable[IGrouping]”.
Its rather this:

'System.Collections.Generic.IEnumerable`1[System.Collections.Generic.IEnumerable`1[System.Int32]]'

The error is this:

Main.xaml: Cannot assign from type 'System.Collections.Generic.IEnumerable`1[System.Collections.Generic.IEnumerable`1[System.Int32]]' to type 'System.Collections.Generic.IEnumerable`1[System.Linq.IGrouping`2[System.Int32,System.Int32]]' in Assign activity 'Assign'.

methodSyantaxVB

However when using method query there is no error and the return type is correct:

'System.Collections.Generic.IEnumerable`1[System.Linq.IGrouping`2[System.Int32,System.Int32]]

Calling libraries fails with Studio 23.10

$
0
0

Hi everyone (Happy New Automation Year!).

We have migrated to Studio 23.10. Since then, calling our own libraries from robots published on our Orchestrator fails.

Everything works fine from Studio itself. Our libraries didn’t change. They have only been republished with the latest version of Studio and its packages (23.10.3).

Everything was absolutely fine with Studio 23.4 and if we downgrade Studio to this version and republish everything (Libraries etc.), it works again.

Brand-new packages created with Studio 23.10 and with no call to our Libraries are also working fine.

In a nutshell, this is only when using our libraries since Studio 23.10 and from robots published on the ORCH that fails.

Here is the message we get from the ORCH:

HELP! ;o)

Sql, Data Table issue: "Execute query : Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."

$
0
0

Scenario:

When executing a query I’m getting this error when I try to get a column containing a string:
**Execute query : Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints.**

Being completely new to UiPath, I did not yet find out how to disable these constraints.

Steps to reproduce:

My flow is as follows:

  1. Connect → 2)execute query → 3)For each row (where I use write line row(0).ToString)

  2. My connection is an ODBC source

  3. For testing my query is as simple as: “SELECT productname FROM products”
    This works fine on some columns but many (string) columns result in the error.

I tried adjusting the flow to first set a type for a column name:
Connect → Build Data Table → Execute query → For each row
In ‘Build Data Table’ I added 1 column of string type with column name “productname” (the one I use in the query). This did not solve the error.

Studio/Robot/Orchestrator Version:

UiPath Studio Community Version 2016.2.6344 Stable

OS Version: Windows Server 2012 R2 Standard 64-bit. .NET 4.0.30319.42000

Hopefully someone can point me in the right direction, or can make some suggestions what to check

You are calling the Computer Vision server too often

$

Hi!

So I’m experiencing this issue with UiPath where it runs just fine but at random points during the program it just decides to either never click or miss a click which causes the robot to go to next step where it has to find a UI Element on another window or another page in the SAP client but since it never clicked or missed the clicked (one of the two, I’m not sure if it misses or just doesn’t click) the robot throws me an error about not finding the element. This issue is random and can happen at any time. It has happened after 1 minute or even 10 minutes it’s absolutely random, I tried messing with selectors and delays to see if it was too fast for SAP to load in everything but that was not the case. I’m using CV elements for this as it was the only thing that could detect buttons and text fields to my liking within SAP.

Misleading, inconsisten missing variable errors on activities

$
0
0

Studio inconsistently displays, or doesn’t display, the exclamation/warning red and yellow messages at its will when there is being used a variable name that is not set. Exemple:

Look at these two screenshots. I cut and pasted these two activities from another part of the project. I knew it was using a variable name that didn’t exist in that context, but no warning was being shown. When I double clicked on the “Parameters” or the “Expression editors”, the warnings where shown up.


Then, I cut and pasted those same activities in a different area of the workflow. And look:

Immediately the exclamations and warnings popped out.

This behaviour is misleading, prone to errors, confusing, annoying and not up to a paid software that costs a fortune.

IMAP access to mail account fails

$

Hello,

I have used an IMAP activity with the following parameters

  • MailFolder “Posteingang” / “Inbox”
  • Port 993
  • SecureConnection “StartTlsWhenAvailable”

to connect to an IMAP mail account. It tries for approximately 40 seconds and the returns the error code “The IMAP Server has unexpectedly disconnected” (Exception Type: ImapProtocolException).

When I use the same settings on the same PC with a thunderbird mail client it works fine and all mails could be read… and Telnet connection to the server / port is also ok.

Unfortunately my collegues from the mailing Team have no clue what is the cause.

Any help appreciated,
Claudius

Error Enumerating files from SFTP Server

$

Hi,
I’m using UiPath.FTP.Activities to download files from an SFTP site. When I enumerate objects, I’m receiving the following error:

RemoteException wrapping System.NotSupportedException: Unsupported object type encountered.

I have the Input Remote Path using a String variable, and the Output Files using a IEnumerable variable type:

image

If I change the Remote Path to “/” I receive a “Permisson denied” error, which is expected because I don’t have access to the root of the SFTP server.

I’ve tried testing using a different SFTP site (test.rebex.net) and I’m able to enumerate files without any issues.

The provider is using Core FTP and they have indicated that they see me successfully listing the files in the directory just before I receive the error message at the Enumerate objects step. Any thoughts as to what would cause this error? It’s puzzling that it works for one site, but not the other.

Thanks in advance!

Hello,

I just started using the UiPath.Workday.Activities package. I get an error each time I launch the UiPath project:

NU1101: Unable to find package ActiproSoftware.Wpf

The activities seem to be working fine but the error is disconcerting.

I’ve tried:

  • regressing back through the Workday.Activities older versions.

  • verifying that my .net framework was current

  • uninstalling UiPath, removing all uipath .nuget packages and reinstalling

Any ideas?

POST jpeg via HTTP Request - corrupted file

$

I’m trying up POST jpg-files via REST API but doing it from UIPath results in an image-file that can’t be read. The server receives the file but as “mime”: “application/octet-stream”,
If I do the same operation from Postman the file is perfectly posted as “mime”: “image/jpeg”.
I can not understand what is wrong. I’m told to use form data but when adding that to the headers (Content-Type, Direction: In, Type: String, Value: “multipart/form-data”) I end up with an error message saying:
400 {“error”:“bad_request”,“error_description”:“No uploaded file found. Please upload the file using the multipart/form-data specification”}

Currently I use no headers and no parameters. Only Body format set to multipart/form-data

I’ve read many threads with similar issues but nobody seems to have sorted this out. Anyone succeeded? Since it works so well from Postman I’m starting to think that HTTP Request may be buggy.

I have a problem that isn’t blocking, but it’s annoying.
I have a Workflow where there is a Syntax error on a SQL Query activity.
I can’t figure out where.
Is there a “quick and easy” way where it is found, without reading all the UPDATEs present, which are over 500?

Below is the error log that UiPath returns to me.
But it doesn’t help me much in understanding where the wrong action is located.

Thanks.

Look at the attached picture.

When I get an error message in an activity prior to executing o debugging, there’s no way I can selec the text explaining the error itself. This is useful when Googling for the error, specially if it is a long one. The tooltip error message disappears when you try to right-click on it, move the mouse pointer or whatever. The one in pink/red on top of the activity properties window is unclickable and unselectable.
