MS_ASSERT(
fingerprint.algorithm != FingerprintAlgorithm::NONE, "no fingerprint algorithm provided");

It seems you did not give a right algorithm when connecting transport.
You'd better check the message body.

[ibc]

@penguinol how do you know that the problem is such an assertion? AFAIR we validate that, otherwise it's a bug since we should never allow the Node app to crash the mediasoup-worker. However, first we need to know whether the problem is this or not.

[ibc]

@mluketin can you please print the object you pass to transport.connect() method?

[mluketin]

Thanks for fast response from both of you.

@penguinol thanks for finding the issue. You are correct.

This is the JSON I receive from client: {"role":"server","fingerprints":[]}
So the object I pass has an empty array of fingerprints and it causes worker to die. (I also did a manual test to confirm this error).

It is obvious I also have some error on client side but I think this should also be handled in mediasoup so it doesn't crash the worker.

Thank you once again!

[ibc]

Thanks, guys. Fixed in 3.6.37.
