NullPointerException during export in WebAnno format #3679

ziorufus · 2023-01-04T11:02:57Z

Describe the bug
I got a NullPointerException error when exporting one or more files having one relation between entities.

To Reproduce
Unfortunately I cannot reproduce the problem from scratch. I set up my annotation task with 7 layers and a lot of rules, and when I try to export in WebAnno format a document containing a relation between spans I got an error.
The problem does not appear when exporting in other formats nor exporting in WebAnno when the document does not contain relations (only spans).

Screenshots

Please complete the following information:

Version and build ID: 24.3
OS: Linux (Ubuntu Server)
Browser: Chrome

The same problem happens when exporting the whole project.

reckart · 2023-01-04T11:08:27Z

The stack trace from the initial description is from an export via the export dialog on the annotation page. Unfortunately, that trace does not go deep enough into the code to see where the NPE is happening. Could you please post a stack trace from the project export so we can check if there is more to be seen?

reckart · 2023-01-04T11:08:59Z

Also, have you tried running the CAS Doctor from the project settings over your project to check for inconsistencies?

ziorufus · 2023-01-04T11:09:17Z

I run the CAS Doctor: no issues shown.

ziorufus · 2023-01-04T11:23:10Z

This seems a good news, except that I can't solve the issue by upgrading INCEpTION :(

reckart · 2023-01-04T11:24:02Z

Well, not yet :) Once I found a fix and released a new version, you could do that - or possibly I find a workaround...

ziorufus · 2023-01-04T11:24:53Z

Thank you very much for your help!

reckart · 2023-01-04T11:29:51Z

Ok, so the problem here is that you are using a multi-value string feature in at least one of your layers. WebAnno TSV 3 is a legacy feature in INCEpTION. The format is no longer updated to support new things in INCEpTION and that includes support for multi-value features. So the bad news is that this is expected behavior (although the error message is not helpful) and there are actually no plans to fix that.

Can I motivate you to switch to the preferred XMI CAS (XML 1.0) export format instead?

ziorufus · 2023-01-04T11:31:17Z

Just another thing. When I export the file without arcs (only spans), I got a layer that does not exist in the project and some weird annotations in all the sentences. Is it normal?

List of layers:

Weird annotations in the TSV (the only one present in the document is "Commento" in second sentence:

reckart · 2023-01-04T11:32:33Z

How do you export without arcs?

ziorufus · 2023-01-04T11:33:15Z

Thank you for your answer, this is a bad news since we have some python post-processing tools that read WebAnno format. Anyway, if you think that in the future the WebAnno format won't be updated any more it's better to move to XML, I guess...

ziorufus · 2023-01-04T11:33:54Z

How do you export without arcs?

I manually removed them.

reckart · 2023-01-04T11:34:38Z

We have a nice and convenient Python library to work with the XMI CAS (XML 1.0) format: https://github.com/dkpro/dkpro-cassis

ziorufus · 2023-01-04T11:36:00Z

Ok, thank you, I'll try it!

ziorufus · 2023-01-04T11:43:15Z

Any idea about the presence of NamedEntity layer in the exported TSV (and the weird annotations)?

reckart · 2023-01-04T11:47:41Z

The named entity layer is a built-in layer. My guess would be that you originally had named entity annotations in the project and then deleted the layer. When a custom layer is deleted, the layer definition is removed and after that, all files are updated to the new type system - which as a side-effect removes all annotations of the deleted layer. My guess is that the type definition for built-in layers remains active even if they are no longer shown in the project configuration - hence their annotations are not removed if the layer definition is removed. If you use the dropdown next to the "create layer" button in the project settings to add back the named entity layer, you'll probably see those annotations again.

ziorufus · 2023-01-04T11:49:01Z

Ok, thank you! I'll investigate it.

reckart · 2023-01-04T12:40:46Z

I'll add a "fix" to this in the sense that the WebAnno TSV 3 export won't crash anymore on such projects, but it will also not include the multi-value features.

- Avoid error when trying to export layers with multi-value string features - Update documentation saying that WebAnno TSV is now considered legacy and doesn't support everything
