badcachekey No cached serialization found with that key

[cwlin0416]

Hi
I use this extension with VisualEditor, but error occurred when saving page.

My MediaWiki version: 1.31.0
Following is api.php reponses:

1. {"visualeditoredit":{"result":"success","cachekey":"f60552e9de0a8b27ef1a0c7c853c35d2"}}

2. {"error":{"code":"badcachekey","info":"No cached serialization found with that key","*":"See https://wiki.skymirror.com.tw/api.php for API usage. Subscribe to the mediawiki-api-announce mailing list at <https://lists.wikimedia.org/mailman/listinfo/mediawiki-api-announce> for notice of API deprecations and breaking changes."}}

I saw the same error, and I do not know what causes it. I'll start an issue on visualeditor talk page. For now you can change the wgSlackSendMethod to file_get_contents to bypass the issue.
