No Action Header found with namespace

[NaurozAhmad]

I'm working with SOAP for the first time and ran into this error: "No Action header was found with namespace 'http://www.w3.org/2005/08/addressing' for the given message."

I simply created a client and tried running a method and then I receive this error.

I also tried adding Soap header using function client.addSoapHeader() but that caused another error saying Bad Request.

I am still facing this issue "$value":"No Action header was found with namespace 'http://www.w3.org/2005/08/addressing' for the given message"

Hi, im having the same issue in the version 3.4.3, im calling the function 'setSOAPAction' but seems that it doesn't care.
