Migrate/pull: inline comments in datafiles are not stripped

[gnzjgo]

Description

When migrating datafiles that contain inline comments (using #), the parser includes the comment as part of the value.

Example

KAFKA_CONNECTION_NAME kafka # The name of the .connection file

The migration parser reads the connection name as kafka # The name of the .connection file instead of just kafka, causing:

Datasource references missing/unmigrated connection "kafka # The name of the .connection file"

Expected behavior

Inline comments (# ...) should be stripped when parsing datafile values. This likely affects both tinybird migrate and tinybird pull.
