Troubleshooting Documentation Errors

React Hook Errors

If you have installed the dependencies in the root of the Medusa repository (that is, if you have a node_modules directory at the root of the Medusa repository), this will cause an error when running the documentation website.

This is because the content resides in docs/content. When that content is being imported from there, a mix up can happen between the dependencies in the root of the Medusa repository and the dependencies in www/docs which causes an invalid hook call error.

For that reason, when the start and build scripts in www/docs are used, the clean-node-modules script is called. This script deleted the node_modules directory in the root of the Medusa repository.

Out of Memory Error

If you receive the following error when you run the build command in www/docs:

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory

This is because of an ongoing issue in Docusaurus that occurs in large documentation websites. As it is still not resolved, the workaround would be to change the memory limit for Node.js while running the build command.

To do that, run the build command with the NODE_OPTIONS environment variable set:

NODE_OPTIONS="--max-old-space-size=8192" npm run build
