Rasa-X tracker store not working for rest api on Slack

We have a Rasa-X project which is using intranet-facing slack using rest api call, instead of the standard internet facing slack. We have not used the rasa-slack connector but have our own shell scripts that connect Rasa-X to slack via a flask app. This is done due to organization’s security concerns. Now, the issue is we are unable to store conversations from the api in the tracker. Anyone faced a similar issue or any idea how to deal with it? we are planning to use postgressql and kuberetes cluster.

What Rasa endpoint are you using to post user utterances?

If you’re using the REST webhook to the Rasa production server it would look something like this:

curl --location --request POST 'http://localhost:5005/webhooks/rest/webhook' \
--data-raw '{
  "sender": "postman",
  "message": "hello, I'\''m Greg"
