Workflow Batch Execution Problem

[hwwangf]

Dear KNIME Team,

Is any possible to auto run workflow by batch mode which flow has “call local workflow node” , my testing failed.

The subworkflow have “image to report and Data to report” birt releated node.

As far as i know, workflow has “call local workflow node” can’t use batch execute mode, correct?

My purpose is auto generate birt report (ppt、pdf)by bat file rather than use KNIME server or KNIME business hub.

reference flow

ipazin/Public – Multiple Reports

Thanks in advance!

Sincerely,

Willy

Hi @hwwangf ,

I was playing around with the “Call local Workflow” node, too. I was trying to execute it in batch mode but couldn’t get it to run. Then I came across this post from February this year that may (? ) be relevant to you:
https://forum.knime.com/t/execute-workflow-with-command-line-execute-failed-cannot-determine-id-of-local-mountpoint/61560/2

Like I said I ran into some problems with calling the nested workflows in batch mode:

“C:\Program Files\KNIME\knime.exe” -nosave -consoleLog -noexit -nosplash -reset -application org.knime.product.KNIME_BATCH_APPLICATION -workflowDir=“C:\Users\XXX\knime-workspace\2020_08_10_Multiple_Reports_Parent_Workflow”

It returned the following message in the knime.log:

java.io.IOException: Cannot determine ID of local mountpoint
[…]
Caused by: java.lang.IllegalStateException: Cannot determine ID of local mountpoint

When I used the mountpoint connector as shown in the linked thread, I could successfully execute the nodes. I’m not sure whether our problems are the same but maybe you can have a look.

I’m currently on KNIME version 4.7.5 with updated nodes, and I think that the type of image that you import might be relevant, too (embedded vs URI vs …).
