If you noticed your deployment crashed with a "webpack: not found" error, then you'll need to make two simple changes. First, add the following to your \`package.json\` file: ``` "scripts": { "postinstall": "cd client && yarn install" } ``` Add the following line to your app's Deploy Script just before the `rake assets:precompile` line. ``` rbenv exec bundle exec bin/yarn ``` Save your Deploy Script and your new deploy should successfully compile your assets. react\_on\_rails clobbers the default Rails assets:precompile command which means the dependencies for your app are not installed automatically anymore. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://hatchbox.gitbook.io/hatchbox/apps/react-on-rails.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
