Unknown file store handler

KNIME Analytics Platform
1

Hi all,

I'm using a chunk loop containing a wrapped metanode that again contains a chunk loop (because of the need to convert the current row to a variable for input in Global Thresholder node of KNIME Image Processing). When running that workflow, I'm getting multiple errors:

ERROR Loop End    2:84  Unknown file store handler to UUID e63fdfa8-96e9-4ddc-9d49-aa4f2b3504f3

Is this a bug? How can I work around this?

Best,

Jan

This is a known bug with Wrapped Metanodes in Chunk Loops. We already investigating the problem and try to fix this as soon as possible. Thanks for reporting Jan!

PS: Workaround... use a Meta-Node.

Thanks Christian, as always :)

This is a known bug with Wrapped Metanodes in Chunk Loops.

So I cannot use Simple Streaming anywhere within a Chunk Loop currently (because it requires wrapping metanodes), can I?

I'm afraid not until this bug has been resolved. But we are working on it! Sorry for the trouble!

Hi Jan, this will be fixed in version 3.1.2.
