javascript parameter seems not to work with default configuration

[volphy]

My environment:

• OS: macOS Ventura 13.5.1
• Python: 3.11.5
• mkdocs: 1.5.2
• mkdocs-material: 9.1.21
• mkdocs-mermaid2-plugin: 1.1.0

My plugin configuration of my mkdocs.yaml file looks as follows:

plugins:
  - mermaid2:
      javascript: javascripts/mermaid/10.4.0/dist/mermaid.min.js

extra_javascript is not used in my configuration file.

Building HTML files using mkdocs works and no errors/warnings are emitted.

However, when I preview generated HTML files locally using IntelliJ IDEA & Google Chrome it mermaid diagrams are not rendered properly and the following error message is visible in Google Chrome Developer Tools:

Refused to execute script from 'http://localhost:63342/access-api-doc/site/authentication/javascripts/mermaid/10.4.0/dist/mermaid.min.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

Am I missing something?

Judging by the port number, it seems you are using Pycharm's built-in web server or something similar?

Try to use mkdocs-serve instead, and see what happens?

Could you make a copy of the call to mermaid.js in the HTML page?

You are right. I use IntelliJ IDEA Ultimate (w/ Python plugins enabled).

Using `mkdocs-serve --clean --strict' generates the following logs to standard output:

As versioned mermaid.min.js I use the file copied from this CDN:
https://cdn.jsdelivr.net/npm/[email protected]/dist/mermaid.min.js

cURL equivalent of the GET request that failed with 404 status looks as follows:

Thanks. Could you make a copy of the call to mermaid.js in the HTML page?

I have already provided this call (using cURL syntax) in the previous comment:
#86 (comment)

Since the problem does not seem to be related to an issue in Mkdocs-Mermaid2, I am moving this to discussion.

My best advice is to follow the troubleshooting guide.
