I can also reproduce this error with occ documentserver:flush

Any idea how i can remove the corrupted file? I tried reinstalling documentserver_community + ONLYOFFICE without success.

I removed the doc_xxxxxxxxxx folder in der nextcloud data\appdata_xxx \documentserver_community

Running occ documentserver:flush now works.

Same bug here.

This error is coming from the onlyoffice/sdkjs/word/Editor/DocumentChanges.js:340.

There are a few other spots where the error is possible. This was for the Load method specifically, but there are other methods that have very similar code that I didn't fix.

Apparently line 312:

var Pos = oDocument.m_oContentChanges.Check(AscCommon.contentchanges_Remove, true !== this.UseArray ? this.Pos : this.PosArray[nIndex]);

Pos can be greater than oDocument.Contents.length; Setting oDocument.Contents[Pos-1].Next = null will result in an error in these cases.

I was able to fix the issue by changing:

d.fa[a-1].$k=null

to

(d.fa[a-1]&&(d.fa[a-1].$k=null))

at apps/documentserver_community/3rdparty/onlyoffice/documentserver/sdkjs/word/sdk-all.js:7996.

After this change, everything appears to saving out correctly. This could obviously be a more complex, systemic issue within the sdkjs library. Definitely recommend forwarding the issue along to the ONLYOFFICE folk.

Software	Version
NextCloud	18.0.4
Document Server	v0.1.5
ONLYOFFICE	v4.1.4

YMMV.

Having the same problem when using images in the document. I can't open the document anymore.

Just had the same bug. I pressed a couple of times enter on a template and suddenly the page disappeared. Reloading did not work and the document opend in libreoffice was empty. I got this error:

I removed the doc_xxxxxxxxxx folder in der nextcloud data\appdata_xxx \documentserver_community

Running occ documentserver:flush now works.

This also worked for me, but for me the error message was about the document Server only Supporting 20 People.
