Batch operation results in 'Error parsing HTTP message header byte 101 of message System.Byte[].'

[troygNZ]

When calling an endpoint that contains a non 200 response for one of the calls, I get back
Error parsing HTTP message header byte 101 of message System.Byte[].

Note, not for all calls.

at System.Net.Http.HttpContentMessageExtensions.<ReadAsHttpResponseMessageAsyncCore>d__19.MoveNext() at System.Runtime.ExceptionServices.ExceptionDispatchInfo.Throw() at System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) at ODataHttpClient.ODataClient.<ParseMultiAsync>d__18.MoveNext()

Quite possibly similar to the problem seen here
https://forums.asp.net/t/2037342.aspx?Max+header+size+when+serializing+HttpMessageContent

Note, this is for an OData 2.0 endpoint.

@troygNZ Thankyou for your bug report.
But I cannot figure it out the cause. I need more detail.
Would you paste the response full body?

Thanks @iwate

@troygNZ Could you check line break code of the response? It need to be CRLF(0x0d0x0a)

[troygNZ]

Thanks @iwate - I'll check this in the morning. The payload and response I obtained for you was from the OData monitoring tool within SAP C4C, so may not preserve it within the browser monitoring tool. I'll debug and reproduce in the IDE to ensure no tampering of response.
