ChromeiQL Syntax error

How can the following syntax error be resolved:

SyntaxError: Unexpected token < in JSON at position 0 at chrome-extension://fkkiamalmpiidkljmicmjfbieiclmeij/dist/chromeiql.js:60748:23

I see this when I am not authenticated with the endpoint I'm trying to query. It could also indicate the endpoint is generally unavailable or set up incorrectly. You might try a known test endpoint like https://fakerql.com/graphql

Is there any provision for setting Headers? Because I think I will need to set some headers to set the endpoint correctly.

Webiste is not available, getting the same error as @sra-013. Did you fix it?
