TypeError

When running python3 jwt_tool.py -T or -R i get:

Traceback (most recent call last):
File "jwt_tool.py", line 1393, in

raise TypeError(f'the JSON object must be str, bytes or bytearray, '

or

Could you provide a sample token that causes this behaviour? Thanks.

Hey,
I just ran into this same issue when my jwt contained a nested dict object like:

Payload = {
"context" : {
"user" : {
"name" : "Name"
},
"group" : "Group"
},

Switching line 91 in castInput from
newInput = json.loads(newInput)
to
newInput = json.dumps(newInput)

Fixed the issue. (Not sure if it will break further along from this, but it works for my current use-case).

Hope that helps.

I had the same issue working with a JWT (unfortunately given NDA I cannot share) that had nested JSON and this fixed it.

Thanks all, this should be fixed in v1.3.5
