Hello @spaz
The error message is coming from the Logic Apps designer and refers to the outcome of the request for creating the API Connection on how it is not unique or how the designer wasn't able to determine/guarantee the uniqueness of the name. You can determine one of the other by taking the following steps:
- Open the Connection creation UI prompt in your browser (as shown in your screenshot)
- Open DevTools or the equivalent tool open in your browser in an effort the capture connection trace.
- While capturing network activity, fill out the form and hit submit
- If/when the same failure occurs with the same error message, you should see a failed connectivity attempt in the Network trace.
- Drill down into the particular failed connection and locate its Response code.
- Use the following to get a better insight on why the uniqueness check is failing:
-
200
means the name is in use so connection creation cannot continue until a unique name is chosen. -
404
means the name is not in use so connection creation can continue. - Any unexpected code, e.g.,
503
, means that it is unknown if the name already is in-use or not. Connection creation cannot continue since the designer cannot guarantee that the name is not already in use. If you find that the failures are caused by this condition, we recommend that you proceed by opening a support case and working with a support engineer (who has deeper insights into your environment) to troubleshoot the root cause. I hope this helps and please let me know if you have more queries.
