Exception passing a header value to request library Create Session












2















I have the following in my Robotframework keyword:



${headers}=  Set Variable  {"Content-Type": "application/json"}
Create Session sample ${url} headers=${headers} disable_warnings=1


But I'm getting the following error in Create session.



ValueError: not enough values to unpack (expected 2, got 1)


This is not working only for this header. I have tried using



{"Content-Type": "application${/}json"} 


which didnt help.

          What you obviously tried to do is to create a dictionary (to pass as a headers argument), but that's not the way to accomplish this in Robotframework.

          The keyword Set Variable creates a var of type string if you pass an argument that is string-like - it does not deduct that you tried to create a dictionary just by the presence of the curly brackets.



          This is how you can create a real dictionary (a dict (sub)type in python):



          ${headers}=    Create Dictionary    Content-Type=application/json


          When you pass this variable to Create Session it now will be a proper dict, and the keyword shouldn't fail because of that.
