Data Pipeline says Invalid object name even though it exists

Is step 4 reading from the SQL Analytics Endpoint?

If so, my guess is that there is some (varying) delay from the creation of the table in Spark until it is synced to the SQL Analytics Endpoint ("metadata sync").

However, these docs say that the new table should be available immediately in the SQL Analytics Endpoint: https://learn.microsoft.com/en-us/fabric/data-engineering/lakehouse-sql-analytics-endpoint
