Acumatica Integration $Filter tag not working with New/Extended Endpoints with Get Request (tried with POSTMAN) - endpoint

Question

I have created New (as well as) extended End Point for Bill Of Materials screen/module. I want the endpoint to return a single BOMID details , while it is returning all the BOMID with details (when passed without $filter tag of it). When I have included $filter tag as specified in the Integration Document (Acumatica ERP_Integration Guide document) it returns error.
The POSTMAN URL is like ({AcumaticaBaseURL} + "/entity/" + {EndPointName} + "/" + {EndPointVersion} + "/" + {EntityName} + "/" $filter=BOMID eq '{valueofBomID}') which is as follows :
http://localhost/AcumaticaMfg21R2/entity/BOMEP/17.200.001/BOMEntity/$filter=BOMID eq '{valueofBomID}'
I have also tried passing the individual BOMID with the Body parameter in request as JSON, but that also is returning all the BOM details (without $filter tag).
Without the $filter it returns all the BOMID's present in the system; with $filter it returns an error.

I've tried the same with 18.200.001 version endpoint. Its working fine. Can you please try with 18.200.001 or 20.200.001 endpoint version?
please find the below screenshots.
Endpoint: /entity/Test/18.200.001/BillOfMaterials/?$filter=BOMID eq 'BOM000001'
