Running the postman collection, DLT required? #9
Description
DLT Booth required?
My testbed looks like this:
- Connector
provider. - Connector
consumer. - Offering Manager.
I created a docker-compose file where these 3 containers are on the same network (so the offering manager can see one "connector" to use).
While trying to do the POST offerings from the postman collection I got this response:
{
"timestamp": "2025-06-05T16:01:09.773423396Z",
"status": 500,
"error": "Internal Server Error",
"message": "Failed while creating a new DLT entry through the DLTBooth: Failed to connect to localhost/[0:0:0:0:0:0:0:1]:8085",
"path": "offerings"
}From the call
The offering manager output if needed:

I can see that it contacts my connector, but then fails trying to connect to the DLT (as I didn't have one deployed)
Then my question, seeing that your README has this comment:
At this moment, offeringManager only provides a limited set of functionalities to play with offerings, although no support for Offering formatting assessment or DLT interaction is included yet in this version (0.01).
Then a DLT booth is required to simply POST a offering on the v0.02?
Seeing some issues open related to the DLT (like #3 & #6), then there is a way to just use the offering manager without having to deploy the DLT?
