Tech Note 10th February 2021
When updating Matillion ETL to version 1.51, you may find that using job variables in imported API Extract Profiles causes Matillion ETL to give errors citing missing variables.
Advised workaround
Exporting the API Extract Profile in question (from your 1.51 instance) and reimporting it should resolve this problem. A fix for this solution is forthcoming in a standalone release, expected in the coming weeks.
