'Error when trying to retrieve data from network' while everything works fine

Hi,

When opening my PowerApp, I get the following error message: Error when trying to retrieve data from network.

I'm using cohesive dropdowns in my form, so I think the app the trying to find a value for dropdown 2 while dropdown 1 isn't loaded yet.

Loading the items of the dropdowns is just a matter of time, 1 second after the error, everything works fine. Here's my error log:

Is there any way to slow down the process until all items are loaded? Or is it possible to turn off the error messages so the user won't be able to see them?

Thank you for helping me out!

@avater456 - "Error when trying to retrieve data from network" error is caused when enable formula level error management setting is turned on. Can you please turn that off to see the actual error.

Hello @Bilakanti ,

Thanks, didn't know this was possible.

I get the following error: The requested operation is invalid. Server response: Table1 failed: Expression "Department eq null" is not supported.

Department is dropdown 1 in my case, is it possible to set a default value so it's never null?

@avater456 yeah you can set the default property of the dropdown so that it wont be null.

@Bilakanti I tried several things in the default property but nothing seems to work. Any idea what specifically I should put here?

So the issue is not with those being run after the error. I had the same error in a patch function. My issue was data connection(no foreign keys possible on the SQL server we used). Can u send the code u use? I'm also Dutch btw.

Hey , have you found a solution to your issue in the end? I am facing the same issue..
I read in another thread that someone fixed it by changing the source of these cascading dropdowns from excel to a list... But before I try this I wanted to check if you managed to find a solution 🙂
