Investigate Batch test failures with new HttpRecorder #7512

Open cormacpayne opened 6 years ago

cormacpayne commented 6 years ago

With the latest version of HttpRecorder, there are two failing Batch tests:

Both tests succeed during re-record and when run live, but fail in playback locally and on Jenkins. This issue is to investigate the cause of these failures and provide a fix in whatever framework the issue was introduced into.

The current failure is the following:

Newtonsoft.Json.JsonReaderException: 'Error reading string. Unexpected token: StartArray. Path 'Content-Type'.'

The corresponding content data from this exception is the following:

 {
  "Transfer-Encoding": "chunked",
  "request-id": "c0d07c42-bbcb-45f9-bbf7-535a8d631460",
  "Strict-Transport-Security": "max-age=31536000; includeSubDomains",
  "X-Content-Type-Options": "nosniff",
  "DataServiceVersion": "3.0",
  "ocp-creation-time": "Tue, 05 Jun 2018 17:11:00 GMT",
  "ocp-batch-file-isdirectory": "False",
  "ocp-batch-file-url": "https%3A%2F%2Fmatthchrwestcentralus.westcentralus.batch.azure.com%2Fpools%2FtestPool%2Fnodes%2Ftvm-892191217_1-20180605t170754z%2Ffiles%2Fstartup%2Fstdout.txt",
  "Date": "Tue, 05 Jun 2018 23:37:06 GMT",
  "Server": "Microsoft-HTTPAPI/2.0",

    "text/plain"
  ],
  "Last-Modified": "Tue, 05 Jun 2018 17:11:00 GMT",
  "Content-Length": "7"
}

There appears to be an issue with the Content-Type array having two values rather than just one text/plain value.

Reactivating this - these tests still pass in Record mode but fail in Playback. Interestingly the error is different than Cormac shared above.

@markcowl - it would be nice to get this looked at and at least understand if this is some expected limitation of the recording framework, or a bug.
