Hrhr I had the same issue the last days with Pixera. So the answer is: you need the
content-length: 22
This has to be the counting of all used symbols in the command. I just do a pre scriptresult as string, let’s call it
JSON=„Chenjdnjxunwbsi“
lenght=„content-length: „+str(Len(JSON))
Len() counts all symbols but the output is integer so I directly change this back to string for the output.
