SyntaxError: Invalid or unexpected token for the file analysis-worker.js #21467

Closed josevarghese closed 2 months ago

josevarghese commented 3 months ago

Please give us a description of what happened

On two or three websites, we noticed that the Yoast SEO metabox became blank or the Readability tab kept spinning. As a result, metabox is not functioning and the AI feature was not working on those websites using the Yoast SEO Premium plugin.

Note: This issue is to track how many users are affected and to find out the issue causing this, as the issue is not occurring on the lab sites

To Reproduce

Step-by-step reproduction instructions

The below steps cannot be used to replicate it but to mention that the issue occurs when the Yoast SEO plugin is used.

  1. Install the Yoast SEO plugin
  2. Open a post editor, where you can see the metabox becomes blank.
  3. Error on the browser console is 
    lodash.min.js?ver=4.17.21:9 Uncaught SyntaxError: Invalid or unexpected token (at lodash.min.js?ver=4.17.21:9:7828)
at analysis-worker.js?ver=aa04978fbd423b404462:1:267
at self.onmessage (analysis-worker.js?ver=aa04978fbd423b404462:1:331)

Expected results

  1. Yoast metabox is to load without any issues, and the Readability tab is to load without any spinning circles.

Actual results

  1. Yoast metabox becomes blank, and the Readability tab shows the spinning circles

After many unsuccessful tests, we reproduced the issue and found it occurs with invalid response headers. When the server marks JavaScript files with the content-type of application/javascript; charset=utf8mb4, it breaks in Chrome but not in Firefox. Note that usually this value is just application/javascript.

We confirmed that changing the value to known invalid charset (random string) produces the same behavior which means that the charset utf8mb4 is not valid as it's rarely used outside of SQL. Setting it to a valid charset directive like utf-8 resolved the issue in our test environment.

Although response headers are commonly set within your web host control panel, WordPress security plugins may offer these features. Please modify the behavior to use a valid charset.
