Hello,

Welcome to the community!

Please attach your module’s output bundle so we can assist you further. Instructions

In the meantime, make sure you’re using straight quotation marks:

"

not smart quotes:

“”

This is a common mistake with JSON. The correct body should use straight quotes, like this:

{
    "agentId": "36dbd931-311b-46cd-988d-05062fbe4f66"
}

Have a nice day!
