I have a workflow which includes a @SignalMethod and it is awaiting a signal to this to allow the workflow to proceed.

I can observe that the workflow is in the Running state from the Temporal UI version 2.2.3. When I click on the button “Request Cancellation” there is a dropdown option “Send a Signal”. This prompts me with a form containing:

Send a signal

1. Signal name \*
2. Input (only JSON payloads are supported)

I’m not sure what to supply here. The only response I can see is the error **temporalproto: (line 1:45): unknown field “params”**
