Custom API Update Swagger Error: The gateway did not receive a response from 'Microsoft.PowerApps'

[michowl]

I am having an issue updating my custom API's swagger file in the PowerApps custom connections area.

After completing the first page (uploading the swagger.json), I fill in the AAD Authentication details for the API (Auth Type: AAD, Client ID, Client Secret, Login url, Tenant ID and Resource URL). Same settings as I always use for this connection.

I hit Save and the blue "Saving..." bar appears and stays for about a minute, at which point, I get the red error bar with the following message: "Custom API Update Swagger Error: The gateway did not receive a response from 'Microsoft.PowerApps' within the specified time period."

Hi Michowl,

Instead of updating the custom API's swagger file, can you try to delete the connection and add a new one? Which is the safe way to do it. 

Regards,

Issue seems to have resolved itself after two days. I already do delete and recreate the connection after updating the CustomAPI. If the Edit CustomAPI feature does not work or is not recommended, it should be removed.
