Hello @khill-fbmc!
Both of @joao_boldtech solutions should work, as you mentioned you would have to stringify/JSONify the data which is not ideal.
I have reported this bug to our eng team to fix as it is the linter which thinks there is an error in the object when there isn't one, as it will run fine but will show red.
As @jg80 linked to the other post where I investigated this, if you add in a ; inside the object the error message will go away.
{"status": "OK"; }
Should work for your example, I noted in the bug patch note that it should be a comma separating key-value pairs and not semicolon separated, hopefully this will be fixed on our end soon!
