Insufficient BPP Callbacks in ONDC TRV11 Domain Pre-Production Environment

[iliyas-kiwimesh]

Issue Description:

We are currently encountering a critical issue with our BAP implementation where we are receiving only 2 callback responses from BPP clients after sending search requests. Both callbacks are returning negative responses (either NACK or location unserviceable errors), preventing us from proceeding to subsequent steps.

Current Behavior:

We send a valid search request from our BAP (pre-prod-api.xxxxxxx.io) to the ONDC gateway
We receive only two callbacks:
From metrobox.preprod.triffy.in with error code 30008 "Location unserviceable"
From pramaan.ondc.org/beta/preprod/mock/seller with error code 404 "There is no such route connecting these stations"

Expected Behavior:

We should receive multiple callbacks from different BPPs with actual ticket/service information to present to users, allowing them to select and proceed with booking tickets.

Additional Information:

We've observed that callbacks work properly only when testing through the Pramaan testing tool
Outside the testing tool, we receive no automatic callbacks with actual service data
Our BAP ID: pre-prod-api.xxxxx.io
Our BAP URI: https://pre-prod-api.xxxxxxxx.io/beckn

Questions:

Are there active BPPs in the pre-production environment that should be responding with actual service data?
Is there a configuration issue with our BAP setup that's preventing proper callbacks?
Do we need to include specific parameters in our search request to get responses from relevant BPPs?
Could you provide a list of active BPPs in the TRV11 domain that we should be receiving callbacks from?

We would greatly appreciate your prompt assistance with this matter as it's blocking our progress in implementing the complete booking flow for our users.

Thank you for your support.
