MissingRefError Can't Resolve Reference from ID

I am trying to validate my data using Ajv library. I have multiple types specified in JSON Schema: SetUserAccountDataPayload, UpdateUserAccountDataPayload, RemoveUserAccountDataPayload and so on.
What I would like to do is to be able to access this type definitions like this:

schema.definitions.SetUserAccountDataPayload

But, I got error:

Uncaught MissingRefError: can't resolve reference #/definitions/UserAccountData from id #

import Ajv from 'ajv'; import schema from 'app/features/cross-platform-bridge/types/cross-platform-bridge.types.json'; const ajv = new Ajv(); const validate1 = ajv.compile<SetUserAccountDataPayload>(schema.definitions.SetUserAccountDataPayload); const validate2 = ajv.compile<UpdateUserAccountDataPayload>(schema.definitions.UpdateUserAccountDataPayload); const validate3 = ajv.compile<RemoveUserAccountDataPayload>(schema.definitions.RemoveUserAccountDataPayload);

Schema:

Any ideas, I can't make it work?
