Make errors / Schema
Validation failed for 1 parameter(s). Missing value of required parameter 'key'
Cause
A required parameter in a downstream module is mapped to the wrong upstream variable, or the upstream module produced no output so the mapped variable is empty.
Fix
Open the failing module and re-check each mapped field references the correct bundle from the correct upstream module. Run step-by-step and inspect each module's output bundle before mapping. Add a filter/Router before the module so it only proceeds when the required value is present.
