error reading JWE_PRIVATE_KEY

[dianacamacho]

When following the migration guide instructions to generate and copy the RSA key for the new JWE_PRIVATE_KEY env var, getting "LpTokenAuth::Error - Your private key is formatted incorrectly."

Sounds like @dschadd is already aware and working on a fix, but just adding details here for doc purposes
