When I try and submit a form in PowerApps I get this error now and I have no idea why:
Could you please share more details about the data source here?
There is no HTTP error code 0, this error code should be returned by the Service API, which should mean Server no response, or request timeout.
Also there are some limits within PowerApps:
Limits and configuration in Microsoft PowerApps
How long it takes for the error message to pop out after the submit action?
Turns out it was a simple mistake. I had added a PowerApp flow early on in developing the app, but then just removed the flow a few days ago, but I forgot to remove the call to the flow from the function.
