Update: The JSON Editor now supports inline expressions!
The JSON data format currently does not support inserting a variable. If your original screenshot showing the logs was for JSON argument, then it makes sense that it showed the raw {{$context.response.data.result}} string as it is not currently translated. I can look into what it would take to support that, but it’s not something I’ll be able to get to immediately.
In the follow-up reply that showed a string argument that has a variable in it, that should be handled fine from the SharpTools side of things and your SharpTools logs should show the context variable being parsed and injected as expected. From what I understand, the driver doesn’t seem to handle that format though?
Have you tested the exact same format that worked as a JSON argument type {} (from the second part of the second screenshot) as a string Aa to verify that the driver isn’t handling the JSON data formatted as a string?
Have you watched the driver logs to see how it is handling the arguments that are being passed to it? Considering the string format of an object has worked for other device types, I suspected that maybe the SmartThings API was inherently handling the parsing of these requests, but it’s possible that the parsing is something they coded into specific drivers. In which case, I wonder if Mariano would entertain parsing a string formatted JSON object. I think the first step here is identifying what the driver is actually seeing though.
