Lua runtime error if token header without spaces is provided (regression since 1.7.6)

[konstantin-smolyakov-idt]

Environment

• lua-resty-openidc version: 1.7.6-3

Expected behaviour

A token validation error is returned (resulting in 401 response).

Actual behaviour

A runtime error occurs and 500 response is returned:

/usr/local/share/lua/5.1/resty/openidc.lua:1654: attempt to perform arithmetic on local 'divider' (a nil value)

Minimized example

Send a bearer token without spaces, e.g. like this

Authorization: Bearer12345

Has this been released, and if not, are there any plans to release it?

I'm currently hitting this bug, but latest released version (1.7.6-3) doesn't seem to include this fix yet.
