senderId in lower case?

I’m using Chirpstack Network Server v3, and when trying to use passive roaming, I’m getting an error:

level=error msg=“roaming: SenderID does not match client-certificate CommonName” common_name=E0xxxx ctx_id=9716e04c-0798-4583-9f6b-1edf3a943bea sender_id=e0xxxx

NOTE- in the error about I’ve replaced the last four digits with x’s

Should I be specifying Hex using lower case alpha char in the.toml files and when creating certs?

Yes, it looks like the sender_id is sent in lowercase where the CN is in uppercase, which is causing the error.
