Unable to find the schema at...

[JamieKitson]

I am trying to use the generatejsonschematypes tool against this JSON schema. However, for virtually all paths as the --rootPath parameter I get back Unable to find the schema at... is there something wrong with this schema or is there a limitation of the tool or am I using it incorrectly?

Your schema contains a $id keyword for each of the definitions. This forces each of them into their own scope - so where you use your $ref keywords in the form #/definitions/[whatever] they are relative to the root of the current scope, not the root of the whole document. This is why everything with a $ref is apparently unresolvable (it actually is! 👍).

You can find out more about $id, and how it changes the base URI, in the json schema documentation

If you want to use $ids for everything, I recommend using URNs instead of fragments, and then explicitly use the URN. Or eliminate the IDs completely unless you really intend them all to be unique scopes.

For example, here's an example removing the unnecessary $ids.

application.json

Then I can generate code like this:

generatejsonschematypes.exe --rootPath '#/definitions/Agent' --outputPath ./Model --rootNamespace Feature410 .\application.json

@mwadams Thanks very much.

I'm now getting Unable to parse generated type:

Ah! Now, that is a bug that I've just fixed in 4.0.0-preview, and will backport to 3.1 today.

You have large numbers of anonymous inline schema that overflow the maximum identifier name length. I'll push up a fix today.

@JamieKitson:

I'm about to push a fix for this issue. It should be available in the next hour or so.

Also, note that if you are getting overlong and complicated names for some of your inline schema, you can use the extension keyword $corvusTypeName to set an explicit type name for them!

Fixed in 3.1.1 and 4.0.0-preview.9
