Data connection error for unused data connection

[Jake2]

I was clearing out some unused data connections for a dev SQL Database. Once I deleted the connection I started recieving this prompt/error that I cannot resolve.

What I have done:

1. Cleared browser cache 
2. Recreated all SQL Database connections
3. Relsolved any connection errors in my flows and republished
4. Removed flows from app and reinstantiated them
5. Resolved any data source errors in my app and republished

I am still recieving the error above and I have no errors from within my app. Is there a way to troubleshoot this further?

Hi @Jake2 ,

Do you mean that you deleted the connection with SQL and then recreated the connection, but met this error?

If so, since you deleted the connection before, recreating connection is not enough.

You also need to reedit all the formulas about this connection.

Please make sure that the new connection's name is the same as the one that you use in the formula.

Here's a similar issue for your reference:

Hi @v-yutliu-msft 

No, I recieved this error after I deleted a old SQL Database connection that was no longer needed. On my next visit to the app I recieved the error above. In a failed attempt to resolve the connection error I recreated the old SQL Database connection.

If there is a issue with a formula ie. referencing a connection that is no longer availible, shouldn't there be a formula error in the application checker?

Currently I have no formula errors.

Thank you,

Jake
