Very unstable version v0.20

[Pelayo-Reguera]

Honestly, I don't know what this error means, but it doens't allow me to finish the pipeline (see details). Apart from that, it's quite unstable the application, because now de GUI gets freeze like 5 or 10 times a day. I will be posting the errors if the console says something, but for the moment, it would be nice to not freeze the screen while trying to load execution information of previous pipelines or workflows executions. For example, if I change to the execution perspective and needs to take a time until the download completes all the executions, it would be nice to have a progress bar and during the download be able to keep working.

By "very unstable v0.20", I assume you mean you found a very specific issue in the Neo4j execution information location in Apache Hop 2.20.0-SNAPSHOT.
If that's the case, can you share a screenshot of your pipeline and let us know if it (at least partially) runs with 0 rows?

[Pelayo-Reguera]

Not really. I mean, everything it's executed correctly and each transform has the corresponding rowns although some of them are empty and that's the correct functionality. But in v0.19 works and in v0.20 keeps writing the messages of the console I shared before. And if try to stop the execution in that moment, then the GUI freezes.

Apart from this, I just remembered that in previous versions I was able to review the configuration of a transform or move the elements of the diagram during the execution and now in v0.20 the GUI freezes.

can you provide a reproducible sample and tell us how your execution information location is configured, a lot will depend on that.

It took a closer look, this was probably caused by PR #8625. Shouldn't be too hard to fix. Create a ticket and we'll look into it.
