Cannot bypass the custom ARCS report parameters when using Groovy REST API

We are using Groovy in EPBCS and REST API to generate the custom report in ARCS.
This ARCS report has 4 parameters, but when we followed the Oracle's guidance, it did not work properly:
https://docs.oracle.com/en/cloud/saas/enterprise-performance-management-common/prest/arcs_rest_generate_reports.html

My four parameters:

And my REST API to call:

I tried to hard code TRANSCATIONDATEHIGH & TRANSCATIONDATELOW paramters with "15-12-2025" or 15-12-2025 or "2025-12-15"

However, the report still exported all the transaction dates, not following my parameters.

What should I do in this case?

Thanks and have a nice day!
