[Palladian] Pooled Web Driver Crashed

[mwiegand]

Hi Philipp,

@qqilihq

Let’s pick this up here at the root - could you elaborate about your issues with the mentioned column or port types?

For failover I write the data into temp tables. Though, Knime, for apparent reason, cannot save the WebDriver column. In case of an error, the WebDriver column or the row is not present resulting in:

Request: Add support in Var Condition Loop End to allow changing table structure

I’d like to bring attention this again as I frequently face this issue as well. Though, I have sufficient fallbacks in place to mitigate changing table specs and actually wonder if there isn’t a bug. [image] Adding to this, the Variable Loop Condition End node sometimes also fails with this error I reported as well: ERROR Variable Condition Loop End 3:1126:0:1003 Execute failed: Encountered duplicate row ID "Iteration 0"

It is also not possible, though I believe the generic loop can pass all varieties, to pass the Web Driver port to start the instance in the inner most loop.

Best
Mike
