Hey Phil,
Thanks for your time, some progress here. When I manually plugged in serverGens in query, it returned the resultsUrl without an error. having said that when I plugged in your formula to extract serverGens, I get 'expression is invalid.
I see you have two formulae and in the second one you are accessing the value of Strip_Query_Params. Do I put both formulae in fx expressions?
my changesUrl looks like this-
https://*****.arcgis.com/********/arcgis/rest/services/Equipment_testwebhooks/FeatureServer/extractC...
If I put just one formula then it says "'The template validation failed: 'The template action 'Sendchangesurl' at line '1' and column '2918' is not valid: "The template function 'body' is not expected at this location.".'.'."
last(split(first(split(outputs(body('Parse_JSON')?['changesUrl']),'&')),'='))
It looks like it is looking for a variable with changesurl. Thanks to you, I am pretty close but not there yet 🙂 Please let me know your thoughts.
