The error message as running the search

[qinggrain]

Why I run a search in Webscrapbook and got the following message.

Scrapbook “scrapbook” seems to have an outdated fulltext cache. Click me to update it and then refresh this page.
Error: The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

What is the version of your OS, browser, WSB and PyWSB?

Do you see any error in the server log?

Again, What is the version of your OS, browser, WSB and PyWSB?

[joshuagau]

Version information

Python 3.9.6 (tags/v3.9.6:db3ff76, Jun 28 2021, 15:26:21) [MSC v.1929 64 bit (AMD64)] on win32

webscrapbook 2.7.2

Browser:
Microsoft Edge
版本 146.0.3856.84 (正式組建) (64 位元)

[danny0838]

Please update your WSB extension and PyWSB to the latest version and try again.

If the issue still persists, please provide the <scrapbook directory>/tree/fulltext.js file (or similar file if you have tweaked the paths in the config), or at least the item which looks like:

 "20250930*********": {
  "index.html": {
   "content": "..."
  }
 },

[qinggrain]

Here is the file fulltext.js
there seems some problems, but I don't know how to fix.

fulltext.js

[danny0838]

@qinggrain Your file has corrupted bytes since line 6383:

...
})�單能見度已看到2027年。 ..."
  }
 }
})

Delete content since the third char (i.e. �單能見...) to the end of the file should fix the issue.

Unfortunately there is no sufficient information to know how this issue has happened. Please update your PyWSB and WSB browser extension, and report if the issue reoccurs.

[qinggrain]

It works! Thanks very much.
