Hi Team,

I am getting this error. While running it via batch file, I am getting this error. Can someone help me out?

“column expressions” not available from extension “knime expressions” (provided by “knime ag, zurich, switzerland”; plugin “org.knime.expressions.base” is not installed)

And if you run it via the client, does the column expression node work as expected?

3

Yes, it’s running without any errors.

hi team anyone else have faced the same issue earlier?

even though if i use date extractor facing same issue .

I recommend to include as much (anonymized) information as possible. Like the batch command you’re using, the workflow itself, the list of installed extensions, etc. The more you give the more likely someone will be able to jump in (I can’t since I have not experienced this issue before).

That’s the problem. I am not getting any errors while running on KNIME Local. Whereas when I am calling the workflow via terminal, I am getting this error.

I have copied and pasted the error I was getting, and I don’t have anything apart from that.
I don’t know why I am getting "Node “Column Expressions” not available from extension “KNIME Expressions"
