Describe the problem

I am trying to setup a self hosted netbird instance with Google Workspace as external Idp. I have followed the documentation and updated setup.env file with the correct keys. But management container fails to start with error

Error: failed creating JWT validator: invalid character '<' looking for beginning of value

My setup.env contents is below, with some of the sensitive values replaced with placeholders.

@bcmmbaga Thank you for your response. I tried installing netbird on a new debian installation, and it worked without any errors.
