BIRT--view report-- I got an eclipse error--could you help me with that--Failed to initialize emitter.

Hi all,

I attended today to the L1-DS training, and one of the exercises was about running a Data to Report node.
I ran into this issue:

What can I do?

do I miss any installation package?

Thanks

Hi there @sgs,

welcome to KNIME Community!

Looks like some permission issue. Can you tell me exactly what action led to this error? I assume you did install KNIME Report Designer extension?

Br,
Ivan

@sgs the given information is rather sparsly. That makes it quite difficult to support you.
Maybe you can give some more information about your workflow and the integration of BIRT.
Did the workflow and report work some time ago?
If yes: What have been your actions/changes before error occured?

One possible root cause: Changed tables (structure) of the output of the KNIME workflow which are transferred to BIRT.
