ACS Video Call Recording servercallId API Error

Question

I developed a project that can make video calls with the “Call Recording Quickstart”. When I access the Call Id value from this project and use it in the API, I get this error; Invalid join identity, cannot join call. Status: 400 (Bad Request) ErrorCode: 8527

Content: {“error”:{“code”:“8527”,“message”:“Invalid join identity, cannot join call.”}}

...

Example call id: 34137f27-6459-4626-9c44-756fdde1c311

What could I be doing wrong? I applied all the articles and solution suggestions but I couldn’t get a result.

Answer 1

The error message you are receiving, "Invalid join identity, cannot join call," indicates that there is an issue with the serverCallId that you are passing to the API. Double-check that you are passing the correct serverCallId value.

Additionally, make sure that the call is still active and that you are not attempting to join a call that has already ended.

If you continue to experience issues, you may want to review the troubleshooting information provided in the "Troubleshooting in Azure Communication Services" document.

Answer 2

Nurdan, Firstly, apologies for the delayed response.

I understand you have tried multiple steps to isolate the issue, typically, the error message "Invalid join identity, cannot join call" suggests that there might be an issue with the serverCallId you are using.. If the call has already ended, you will not be able to join it and may receive this error.

What SDK version are you leveraging? Example : ACS Calling Web (JavaScript) SDK - Release History -- This is a sample application to show how the Azure Communication Services Call Automation SDK can be used to build a call recording feature.

Kindly let us know, I'll follow-up with you further.

Nurdan Erdem, Following-up on this, we would need additional info on exactly what you are doing on the server side?

From your description I suspect you are calling maybe this method from the RecordingsController sample?

If this is the case - then the issue might be that you are passing callId (seen on the client side) as opposed to serverCallId (which this method requires).
