Nested key claim name

[meysam81]

I want to know how one can use nested jwt payload in kong?
imagine I have the following payload:

{
    'level1': {
        'level2': 'something',
    },
}

now if I would like to say that my key_claim_name is going to be level1.level2 it says that's not possible through the following error:

{
    "message": "No mandatory 'level1.level2' in claims"
}

@meysam81 Did you ever find a solution to this?

I ended up modifying the underlying source code in the docker container, committing it, and reusing it in my future deployments.

here's my modification:

In the docker container, open the following file:
/usr/local/share/lua/5.1/kong/plugins/jwt/handler.lua

replace the following code:

local jwt_secret_key = claims[conf.key_claim_name] or header[conf.key_claim_name]

with this one:

local jwt_secret_key = claims[conf.key_claim_name] or header[conf.key_claim_name] or (claims["CUSTOM_KEY"] and claims["CUSTOM_KEY"][conf.key_claim_name])
