Workaround: double check your token, use incognito mode in browser.

We should fix this issue by making a better error message in this case.

Reproduce the browser failure with an invalid token, then start from the Apollo Client HTTP path shown in node_modules/@apollo/client/link/http/createHttpLink.js and parseAndCheckHttpResponse.js. Done means this case displays a clearer error message instead of the generic invalid fetch value; no test file is mentioned.
