Azure APIM Fails to Create API from Function App

Question

When I try to create an API in APIM by using Create from Function App, I fill out the fields and click Create. The operation provides the wait dots and comes back in five seconds and says

Could not create an API. Please try again later.

I can create a blank API...but not one from an existing Function App. I have tried multiple combinations, No products, all products, no version, version..etc. No luck.

Thoughts?

Notes

The function in question is an HTTP Trigger.
The function works locally on my development box and in Azure.
APIM Tier is Developer
On that Function app, during Publish in Visual Studio I have reported that attempting to manage application settings before a publish fails and in trying to add a new one causes Visual Studio to unexpectedly close. Manage Application Settings on Publish Related, don't know.

On the APIM blade, when I scroll down to `Logs` and the blade displays, it displays with no logs. Is there a different location to view? — ΩmegaMan, Jan 19 '19 at 16:55
You should select activity logs in APIM blade and filter by the issue time period. Could you share the service name? — JJ., Jan 21 '19 at 17:09

Just a Ctrl + F5 solved the problem for me. Try it! ;)

Didn't expect this to actually work, but lo and behold it surprisingly did. This also worked for me with a different error than the OP in case someone comes here like I did searching for a solution. The error in my case was related to not being able to get the config data from my function app. – Architekt May 26 '21 at 16:08
Also worked for me when I had this issue too! – Matthew Jones Nov 15 '21 at 23:47

I just ran into the same issue because I used Linux (Preview) instead of Windows. When I blew away the Function App and recreated a new one with Windows, my API Manager was able to create an API off it.

We are running Windows but still experience the same issue unfortunately. – RKrogh Nov 30 '20 at 07:48

This seems to still be an issue with Linux based function apps. – Chris Parker Dec 01 '20 at 20:55
Is it possible to setup Linux function apps with API Management using ARM templates? – j-petty Mar 18 '21 at 03:53

Hope you have follwed below link. Kindly check the note, You can import only Functions that are based off HTTP trigger and have the authorization level setting set to Anonymous or Function. https://learn.microsoft.com/en-us/azure/api-management/import-function-app-as-api – Inzi Jan 18 '19 at 06:01

At this time the solution for me was to use Microsoft Edge instead of Chrome.

It seems Microsoft Azure portal is not working properly in Chrome and I noticed issues in several places. Parts of pages are not rendered at all and sometimes even errors like this pop up just because of the browser.

I've seen similar with other Azure tools, where one would have to switch browsers. That is why one never deletes the copy of `Mozilla` they have. – ΩmegaMan Mar 16 '21 at 19:44

I had this same problem.
The fix was both simple and unexpected.

When importing the function app, simply enter "/" in the API URL Suffix field. For me this changed the BaseURL field value. Originally it was just the host, ie http://hostname/. It then appended the endpoint the hostname, http://hostname/endpoint This is done on the "Create Function from App" modal.

I had the same problem when trying to publish my Azure Functions application with several HTTP triggered functions through API Management running on Consumption plan. The plan did not have anything to do with the problem though.

What I did not realize was that my function app was not working properly when browsing it from the Azure portal. I had some configuration errors that prevented the app to work properly. When I resolved those, I succeeded to publish the application through APIM.

So, check that your application is working properly by browsing to it if you run into the problem described in this thread.

The issue was that the function did not actually work.

The Browse button that redirects to the page with the light bulb and the text Your function app version X is up and running did show, but the function still didn't work.

The function error had to be fixed before when importing to the APIM was done.

I had temporarily suspended (or stopped) my Function App. Restarting it resolved the problem.

I hope Azure could improve the error message, at least from UX perspective.
