I have problems in the tests with two functions:

• initSessionByUserToken
• resetPasswordRequest

I do not know if this happens because of some mistake of mine or if it is due to some change that has occurred in the backend since the last time we worked in this library. I'm trying to figure out why this happens and fix it if possible.

I already know what the problems were. In the resetPasswordRequest I tried to make a request to the email "gmanganiello@teclib.com" but it turns out that there is more than one user registered with that email and when dealing with a request to change the password, an error returns. The problem of initSessionByUserToken was a bit easier, it turns out that I was trying to login with my "Personal Token" but the data that was needed was my "API token".
