# Troubleshooting ## Self-Signed TLS Certificate If you are running API Platform on development machine which does not have valid TLS certificate, add `NODE_TLS_REJECT_UNAUTHORIZED=0` before running create-client: ```console NODE_TLS_REJECT_UNAUTHORIZED=0 npm init @api-platform/client --generator typescript https://127.0.0.1:8000/api src/ ``` ## Authenticated API The generator does not perform any authentication, so you must ensure that all referenced Hydra paths for your API are accessible anonymously. If you are using API Platform this will at least include: ```console api_entrypoint ANY ANY ANY /{index}.{_format} api_doc ANY ANY ANY /docs.{_format} api_jsonld_context ANY ANY ANY /contexts/{shortName}.{_format} ``` ## ApiDocumentation doesn't exist If you receive `Error: The class http://www.w3.org/ns/hydra/core#ApiDocumentation doesn't exist.` you may have specified the documentation URL instead of the entrypoint. For example if you are using API Platform and your documentation URL is at [https://demo.api-platform.com/docs](https://demo.api-platform.com/docs) the entry point is likely at [https://demo.api-platform.com](https://demo.api-platform.com). You can see an example of the expected response from an entrypoint in your browser by visiting [https://demo.api-platform.com/index.jsonld](https://demo.api-platform.com/index.jsonld). ## Cannot read property '@type' If you receive `TypeError: Cannot read property '@type' of undefined` or `TypeError: Cannot read property '0' of undefined` check that the URL you specified is accessible and returns jsonld. You can check from the command line you are using by running something like `curl https://demo.api-platform.com/`. ## Dereferencing a URL did not result in a JSON object If you receive a message like this: ```console { Error at done (/usr/local/share/.config/yarn/global/node_modules/jsonld/js/jsonld.js:6851:19) at at process._tickCallback (internal/process/next_tick.js:188:7) name: 'jsonld.InvalidUrl', message: 'Dereferencing a URL did not result in a JSON object. The response was valid JSON, but it was not a JSON object.', details: { code: 'invalid remote context', url: 'https://demo.api-platform.com/contexts/Entrypoint', cause: null } } ``` Check access to the specified URL, in this case `https://demo.api-platform.com/contexts/Entrypoint`, use curl to check access and the response `curl https://demo.api-platform.com/contexts/Entrypoint`. In the above case an "Access Denied" message in JSON format was being returned. ## Docker distribution on Windows and hot-reloading Due to [a long-time known Docker for Windows issue](https://forums.docker.com/t/file-system-watch-does-not-work-with-mounted-volumes/12038), the file changes on the host are not notified on the `pwa` container. It causes the hot-reloading feature to not working properly for Windows users.
