litmus: LitmusPortal subscriber fails to start

What happened:

When connecting the LitmusPortal agent, the following occurs in the log of the subscriber pod:

The fatal error is │ time="2021-07-13T01:54:30Z" level=fatal msg="invalid character 'p' after top-level value"

This happens every time.

The agent does not connect and every time, my subscriber fails on a CrashBackLoop. Could anyone advise?

What you expected to happen:

The subscriber should start normally.

How to reproduce it (as minimally and precisely as possible):

Connect the litmusctl agent with the portal.
