NC29:Fulltextsearch live crash

[prolibre]

Running Nextcloud 29.0.3.4

Several times I have had this error (which caused my fulltextsearch:live service to crash) :

Error: Typed property OC\FullTextSearch\Model\IndexDocument::$access must not be accessed before initialization in /nextcloud/lib/private/FullTextSearch/Model/IndexDocument.php:775

Several times I managed to fix the problem with a simple fulltextsearch:index
but on the last crash it didn't work.

It looks a lot like nextcloud/fulltextsearch_elasticsearch#375

To correct the problem I commented this (line 775 of the file /nextcloud/lib/private/FullTextSearch/Model/IndexDocument.php)

public function jsonSerialize(): array {
return [
'id' => $this->getId(),
'providerId' => $this->getProviderId(),
#'access' => $this->access,
'modifiedTime' => $this->getModifiedTime(),
'title' => $this->getTitle(),
'link' => $this->getLink(),
'index' => $this->index,
'source' => $this->getSource(),
'info' => $this->getInfoAll(),
'hash' => $this->getHash(),
'contentSize' => $this->getContentSize(),
'tags' => $this->getTags(),
'metatags' => $this->getMetaTags(),
'subtags' => $this->getSubTags(),
'more' => $this->getMore(),
'excerpts' => $this->getExcerpts(),
'score' => $this->getScore()
];
}

After correction, everything seems OK.

I had the same issue on a testing instance running NC 29.0.4. Issue occured after I deleted a user. It seems that :live process crashed because fulltextsearch tries to update files of that user which does not exist anymore.
I had to :reset and :index again to solve the issue.
