interceptor interferes with httpclient.operation().pipe() when response is not json

[vigouredelaruse]

hi - sad to report that

• i am using the json refs interceptor against an asp.net core api that can return text/html
• with the interceptor enabled it is not possible to consume endpoints that return Content-Type: text/* - affects raw use of httpclient and swagger generated clients that use httpclient
• error is that rxjs pipes that include httpclient observables block at the http call
• no repro at this time, please indicate if necessary

please advise
