tHMap mapping issue with Talend Job

[waterr]

I am creating a talend 8 job which extracts member data from an API to be replicated. Currently I am running into an issue where my JSON file can not be mapper properly with tHMap. It says "The schema of the "row 5" input payload type connection must only have one column." I am unsure how to fix this, I have tried editing the schema of the row 5 input to only have one column in the input, but this did not solve my issue. I am trying to run the job right now with some Sample JSON data instead of pulling data from the API right now. I would greatly appreciate any help. Thanks
