Try replacing these lines:

Code:

code_verifier = encdec.sha512(mt()):sub(1, 86)
state = b64url(encdec.sha256(mt()):sub(1, 12))
code_challenge = b64url(code_verifier)

With this:

Code:

rnd = encdec.sha256(mt())
code_verifier = (rnd .. rnd):sub(1, 86)
state = b64url(rnd:sub(1, 12))
code_challenge = b64url(code_verifier)
