If authentication token for sysdig provider is expired, the error message is unclear

[duncan485]

When the authentication token for the provider is expired, it returns a vague error: Error: invalid character 'u' looking for beginning of value.

What would I expect?
If the provider can't authenticate, I'd expect the provider to throw an authentication failed error.

What happened?
When provided with expired/invalid credentials, the provider returns a vague error: Error: invalid character 'u' looking for beginning of value

How to reproduce

• For example, create sysdig_secure_posture_zone resource with a valid authentication token in place
• Invalidate the token
• Run a plan
