Send events using REST API - Not appearing in timeline

Question

I'm trying to use the 'Send events using REST API' feature. When I make the POST it responds with a 202 response. But I can't see it in the timeline, I assume it should available almost straightaway.

I've double checked event sources and they seems to be setup correctly. Any ideas  really appreciated! :)

Example curl command:

(I've replaced any sensitive information).

curl --location 'https://<mydomain>.atlassian.net/gateway/api/compass/v1/events' \
--header 'Accept: application/json' \
--header 'Content-Type: application/json' \
--header 'Authorization: Basic REMOVED_AUTH' \
--data '{
"cloudId": "CLOUD_ID",
"event": {
"custom": {
"displayName": "test",
"lastUpdated": "2022-05-22T12:23:45Z",
"updateSequenceNumber": 57,
"description": "testing",
"url": "https: //www.example.com",
"externalEventSourceId": "poc-event-source-custom",
"customEventProperties": {
"id": "1234",
"icon": "INFO"
}
}
}
}'

Discovered this was user error. For starters the year is incorrect. Then subsequence updates did not fix the issue until I changed the sequence number.
