I have a logic app which is triggered by an HTTP call. With this call comes a set of headers, most of them used in different switch statements. Using the Parse JSON action I feed in the headers from the request, they successfully parse (image 1), but for one of the headers (searchType) the switch statement evaluates to null for some reason (image 2). I cannot for the life of me figure out why.
I have tried to remake the logic app from scratch, copy the app to a different environment entirely, and tried to use the expression to access the parsed value instead of dynamic content. When I try the expression I am told it is an invalid expression (image 3). This expression is a straight copy from what is used on the code view.
Any suggestions as to what i can do to solve this?
parsed header evaluates to null
JSON to replicate logic app
