Variable loop end node stuck at 2nd iteration

Hello,

I am extracting data from a db into monthly parquet files stored in a R2 bucket.

At the end of second iteration (#1), while the parquet is well at 100% upload, the variable loop end remains stuck in “queued” state and does not activate the next iteration.

Have been using this kind of sync in several workflows but it is the first time I have such an issue. Anybody experiencing the same issue?

Have seen other posts related to slowness of some end loop nodes, but I have kept it running for 2h without progress. So, it doesn’t seem a matter of slowness.

I am using Knime AP 5.4.4.

Regards,

Sébastien
