KNIME Batch Failures: Error Types / Codes

[ynaveed1898]

Was there any place that I could find documentation for the KNIME Batch error codes? Primarily, I was wondering what Error 1 was and when it occurs, since I have not seen it.

Additionally, I have assumed what errors 2-4 are, so please let me know if I am wrong here and if there are any errors past error code 4.

2 - error with loading variables into batch
3 - error with loading KNIME workflow
4- error within the KNIME workflow

Hi @ynaveed1898 -

I haven’t ever seen an Exit Code 1 in the context of KNIME either, but a little googling indicates that it has do to with multiple or conflicting versions of Java installed. As for the other exit codes:

KNIME Batch File ERROR

Hi @gua_gunners - Exit code 2 occurs if parameters are wrong or missing. So the problem might be that you have some workflow variables that you need to provide values for. Just FYI, exit code 3 indicates when an error occurs during loading a workflow, and exit code 4 indicates if an error during execution occurred.
