🐛 Bug Report

I got this error after I updated the docusaurus version from 2.0.0-alpha.48 to 2.0.0-alpha.64.

Have you read the Contributing Guidelines on issues?

yes.

To Reproduce

1. Download this example repository:
   test-docs.zip
2. run npm i
3. run npm run start
4. see JSON parse error as seen in the screenshots
5. comment out line 6 in docs/home/home.md
6. see error disappear

Expected behavior

The project should start and build as it was before updating to the new docusaurus version (2.0.0-alpha.64)

Actual Behavior

When running npm run start or npm run build I get errors related to the JSON parserin webpack (see screenshots)

Your Environment

• Docusaurus version used: 2.0.0-alpha.64

Hi,

You upgraded Docusaurus and likely many other deps were upgraded too in this process, so it's hard to know the problem and if it's our fault without a repro. If you can try to create the minimal repro case that would be great.

I don't even know what is the content of this json file, and how/where it is consumed, so it's hard to solve.

Hi,

Thanks for the quick feedback. I have updated the bug report description and added an example repository. Hope this helps!

Thanks @nicolas-actyx

It seems we try to load your json file as a static asset like we do for images. Probably make sense. to do so but I suspect there is a conflict between assets loader (file. loader) and code loader (babel loader).

I suggest you use the pathname:// prefix as an escape hatch for such case, to opt-out of the assets loading through webpack and use a regular link instead (which will work as it links to an existing asset in /static)

[This is what causes the JSON parse error](pathname:///schemas/os/node-settings.schema.json)

Thanks a lot for the quick help, just tried it and it works!
