    Hi @moprabthai,

    Could you please tell me that what is the triggerMultipartBody(1)?

     

    If you want to check if a value is null, you could write the null in the Expression tab

    The triggerMultipartBody(1) is from the "When HTTP request is received" module. The problem is that when nothing is sent, the output from that module is output like this:Capture.JPG
