Different behavior for to_json() based on object type

[abouillot-stl]

Hello,

I have UE Capabilities messages following a 5G NR Registration Request.

After retrieving the ue-CapabilityRAT-Container and seting up the Capability message according to the rat-Type, if I try to get the json representation, it work fine for the UE_MRDC_Capability, but I get an error TypeError: Object of type bytes is not JSON serializable when doing the same to UE_NR_Capability.

Attached the sample code showing the behavior, with an eutra-nr and a nr messages. I process both messages the same way, but with a different outcome.

nr_json.py

No sure if this is linked to the content of the message, my understanding of the operation or something else.

Thanks for any hints

Thanks for submitting an issue.
When I run your code, I get no error. Can you please verify the code extract provided, verify your environment and indicate your python and pycrate versions, provide the entire stack trace of your error... Otherwise it will be hard to help.

Hello,

I'm using Python 3.11.9 with Pycrate 0.7.11 retrieved through pip.

Here is the error, after the display of the first element:
Traceback (most recent call last):
File "D:\test_code\nr_json.py", line 1123, in
val = nr.to_json()

This output has been generated with the very same code as in nr_json.py

Thanks
