JWS init error localAuthenticationFailed

[raphaelguye]

From time to time, we get an JOSESwiftError of type localAuthenticationFailed when trying to initialize a JWS object.
The Signer we use is an ECSigner with an algorith ES256.

After some investigations the error seems to be thrown by:

• JWS init
  • EC sign

The errorCode is always -1

Do you have any idea why such errors happens and how we should investigate the problem more in details?

Hi @raphaelguye, do you have a reproducible scenario for us to have a look at? In the meantime you can also look at #173 which was the PR that added this part of error handling, for more details.
