Hello Thiago,

The error suggests that the private key content is either incomplete or corrupted. The privat ekey format must be multiline and using the following structure:

-----BEGIN RSA PRIVATE KEY-----
MIIBOQIBAAJBAIOLepgdqXrM07O4dV/nJ5gSA12jcjBeBXK5mZO7Gc778HuvhJi+
RvqhS..................................................QzhwkDbck

u+zYCJfIjtJJpH1lHZW+A60iThKtezaCk7FiAC4= 
-----END RSA PRIVATE KEY-----

Hope this information helps.

Cheers

Hi, I got the exactly same issue... 

What am I missing? 

"-----BEGIN RSA PRIVATE KEY-----

Hello Lorena,

I had similar problems due to line endings characters (CRLF) or text enconding (non-UTF8). How are you setting the private key in the GetToken server action.
