Hello, what’s up?
In my workflow there is a problem in the node http request in the construction of the json, although the json is correct (I already tested it in postman and it worked) it returns: ERROR: JSON parameter needs to be a valid JSON.
I realized that it only returns this error when there are expressions in the body and I don’t know how to get around it
