Limitations of Flow in PowerApps

I am trying to use a flow I created in PowerApps. The flow inserts a row into an On-Premise SQL database, and then calls a Stored Procedure. The Flow works fine (it has been tested), but everytime I try to add it to my PowerApps I get the following error:

"Failed to Register Service '...'"

I have seen this in a number of posts, but no one has received a clear answer. I am convinced that PowerApps cannot handle certain flow actions. Would somebody provide me with a more detailed list of what can and cannot be done, please?

Re: Limitations of Flow in PowerApps

Hi @Anonymous,

Could you please share a screenshot about your flow's configuration?

Do you add a "Request - Response" action within your flow to return executed result back to your app?

The user @johnmarlowe and @mokhawaja have faced similar issue with you, please check the response within the following threads:

If you have added a "Request - Response" action within your flow, please check if you have typed proper JSON schema within the Response Body JSON schema field of the "Request - Response" action. In other words, please check if there are some columns which did not have its type defined within the JSON schema that you provided.

Please also check if you have defined a PRIMARY KEY within your SQL table.

If the issue still exists, please take a try to clear cache of your browser, then re-add flow connection within your app, check if the issue is solved.


Best regards,

Re: Limitations of Flow in PowerApps


It seems like the flow is working now... I have no idea why because I have not changed anything. I thought also that it could have been a permissions issue because I was using a flow that was shared with me, but, now that the flow is working, I am very confused.
