Failure to Sync Encounters and Observations from CHT to OpenMRS via Mediator

[lorerod]

Describe the bug
Encounters and Observations created in CHT fail to sync to OpenMRS via the Mediator, with an error logged: "Not re-sending encounter from CHT."

To Reproduce

1. Start the docker container using ./startup.sh up-openmrs
2. Follow the steps in OpenHIM Admin Console guide, installing CHT Mediator and OpenMrs Mediator
3. Follow the steps in Local setup of CHT Configuration guide
4. Use the OpenMRS Interop.postman_collection.json with the corresponding dev.json env variables.
5. Change "key": "CHT_ADMIN_USER" to have value admin instead of medic
6. Execute the first six calls in the postman collection:

• Mediator Status
• OpenMRS Api Status
• createPatientIdentifierType
• createDocumentIdentifierType
• CHT Create Patient
• Get FHIR Patient

7. Until this point, the mediator log looks fine. No errors. The last lines in the log:

8. Execute OpenMRS FHIR Sync Patient
9. Everything looks as expected.

• Mediator log:

11. Execute the GET OpenMRS Patient step. It was successful with a response body containing "total": 1
12. Execute CHT Create Report. The transactions log looks as expected:

13. Get FHIR Encounter returned a "total": 1 and Get FHIR Observations should return "total": 2 as expected.
14. Execute OpenMRS FHIR Sync Encounter
15. Mediator log shows an error:

16. Transactions log in OpenHIM admin console look like this:

17. GET OpenMRS Encounter returns "total": 0, expected 1
18. GET OpenMRS Observations returns "total": 0, expected 2.

Expected behavior
The OpenMRS Encounter and Observations should be created.

Environment

• Branch: at the moment of the creation of this ticket, the branch I use is openmrs-mediator
• Client platform: Docker desktop on MacOS Intel

It looks like the polling doesn't start automatically once the channel is added.
I was able to start it by going to the channel and saving it (without making any changes)

[lorerod]

Thanks for the update!
Could we consider going to the channel and saving it as a recommended workaround?
Or is there a fix we should be implementing to ensure the polling starts automatically when the channel is added?
