api_jsonld_context ANY ANY ANY /contexts/{shortName}.{_format}
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 the entry point is
likely at https://demo.api-platform.com. You can see an example of the expected
response from an entrypoint in your browser by clicking visiting
https://demo.api-platform.com/index.jsonld.
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/
.
If you receive a message like this:
{ Error
at done (/usr/local/share/.config/yarn/global/node_modules/jsonld/js/jsonld.js:6851:19)
at <anonymous>
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.
