Registering Error when trying to add a flow

(0) Share

Report

Posted on by Georgiak22

I have the following flow that sends a json body to a Custom PowerApps connector to a custom API. When testing the flow it completes successfully. The same when I test the custom connector directly.

But when I try to add it to a button I have the following error:

Attached you will find the OpenAPI file used for the custom connector.

What can I do? I have already tried:

Recreating the flow Calling it from a different powerapp

Checked and recreated custom connector from OpenAPI file

Checked on the production environment as well, same error.

Read and tried solution in similar threads

I cannot find another way to troubleshoot this, does anyone have any suggestions?

Hi @Georgiak22,

Could you please share a bit more about the result the json function returned within your flow?

I have made a test on my side, and don't have the issue that you mentioned.

The user @johnmarlowe has faced same issue with you, please check my response within the following thread:

https://powerusers.microsoft.com/t5/General-Discussion/Registering-Error-when-trying-to-add-a-flow/m-p/142010/highlight/true#M48780

Please check if the result the json function returned has a proper JSON schema. In other words, please check if there are some columns which did not have its type defined within the JSON schema.

In addition, please check if the response from the Super user @mr-dang within the following thread would help in your scenario:

https://powerusers.microsoft.com/t5/General-Discussion/Error-on-adding-a-flow-run-SQL-query-to-powerapps/td-p/119203

You could also consider take a try to clear cache of your browser, and then re-creatae a new app, then check if the issue is solved.

Best regards,

Kris

Hello @v-xida-msft

I have tried the solutions in all similar posts I could find and no luck. Also it is not the browser cache since I have tried it from 2 different machines and subscriptions. Do you have any ideas, or other means to troubleshoot this?

The flow works on its own fine and other flows using the custom connector are added fine. I cannot see the difference in this one or if there is a limitation I am no aware of.

Thank you!

The official Microsoft Response was that I should not use string as input to the custom connector but instead use Compose - Parse json and this solution resolved my problem. Attached the image.
