When columns are mapped to a picklist defined in non-recurring pay in EC, the form launch fails.
Eg: When Column "Rating" is mapped to a component "example" in ec, the form launches successfully.
However, if the column is mapped to "example.code or example.label", the form launch fails.
This is a product gap and is currently under process as an enhancement request
This is currently not supported by the system.
