Content-Length header already present error in soapUI 5.6.0

I am trying to run a REST API call on SoapUI version 5.6.0 and I'm getting the following error:

I am well aware of past fixes suggested for this, I have tried them all but to no avail.

I cannot run this API without the Content-length header as the server throws a 500 error

My key value pair is as follows:

Content-Length

<calculated when request is sent>

HEADER

METHOD

Hey @hananurrehman,

Are you saying your get two Content-Length headers in your request?

Some headers are dynamically generated and the Content-Length is one of them. Have you tried removing the header youre manuallt adding in to see what happens?

Problem was with my settings, like I thought! Checking the "Authenciate Preemptively" check box in global HTTP settings solved the issue 🙂

Hey @Koepp,

are you answering this or is this a separate issue or something else?

Reason why i ask, what i got from @hananurrehman's message was that there were 2 Content-Length headers being generated in hia request and i wouldnt expect hitting authenticate preemptively checkbox to fix that...??

I got the error to go away (in SoapUI 4.5.1) by checking the Authenticate Preemptively flag in

Preferences -> HTTP Settings -> Authenticate Preemptively
