Custom Connector - failed: { "statusCode": 404, "message": "Resource not found" }

I am constantly getting a 404 error when I am using a webservice from Business Central to build

a Custom Connector with.

 

HMBHEADERTEST.Runitagainsam failed: { "statusCode": 404, "message": "Resource not found" }

When testing, it returns a valid 200 reply. Also in Postman it works.

 

I can see others also have problems with this error, but I have not been able to see from other posts in this forum, what 

the solution should be ?

Hi @HenrikMB ,

Do you mean that when you run an app using custom connector ,you will get 404 error?

This may be caused by many reasons.

Hi v-yutliu-msft

 

The problem with the Powerapps custom connector that can not connect to Business Central is still there, but it is best described in the following thread.

https://powerusers.microsoft.com/t5/Building-Power-Apps/404-error-trying-to-consume-custom-connector...

 

There are mentioned a Service Request #: 120021322000110.

 

Is it possible to get an update from Microsoft about this problem, that for a long time, has been a known issue?
