Describe the bug
Javascript error after sending request.

To Reproduce
Javascript error:

TypeError: Cannot read property 'startsWith' of undefined
    at a.default.e.transformResponse (chrome-extension://amknoiejhlmhancpahfcfcfhllgkpbld/index.js:60)
    at chrome-extension://amknoiejhlmhancpahfcfcfhllgkpbld/index.js:10
    at Object.B [as forEach] (chrome-extension://amknoiejhlmhancpahfcfcfhllgkpbld/index.js:4)
    at module.exports (chrome-extension://amknoiejhlmhancpahfcfcfhllgkpbld/index.js:10)
    at chrome-extension://amknoiejhlmhancpahfcfcfhllgkpbld/index.js:44

Without the extension:

TypeError: Cannot read property 'startsWith' of undefined
    at regeneratorRuntime.mark.regeneratorRuntime.wrap.h.transformResponse (c4f4c8737a6876cf35a9.js:1)
    at 90e58649f81013ae3376.js:2
    at Object.h [as forEach] (90e58649f81013ae3376.js:2)
    at t.exports (90e58649f81013ae3376.js:2)

By default Spring Boot does not send a response body for unauthorized requests - so no content-type is included in the response header I guess.

Expected behavior
401 HTTP error message

Desktop (please complete the following information):

OS: macOS
Browser: Chrome
Version: 81

I can share the URL + Headers for the request privately if needed :)

Hi @jonasbark ,
can you try force reloading the web app and see whether issue exists or not?

Still happens - I only discovered Postwoman yesterday, so it's probably not a cache issue :)

Oops I get the problem.

I will roll out a patch in an hour or so.

It will take a day or two to get this bug fixed on the extensions though (Chrome Web Store verification takes time)

The new transformResponse code expects a content type header to be present which was not there in the request, hence startsWith ran against null.
