Hi @visch I created a complete project with fresh meltano env and everything but still got the same errors. After doing some researches I was able to solve all errors which was showing in terminal. Still pipeline didn't work so I removed the criteo plugin and used pip package to use instead of github and finally pipeline worked and got the messages attached in screenshot. For the loader I got the error to specify "*batch_size_prefernces*" and looking at the repo code I specified "full_table_streams" to be true then it worked. batch_size_preferences: {'full_table_streams': true} But I didn't see any of the rows replicated in stitch, could you please help to understand the cause.
