Cannot read properties of undefined (reading 'getRef') about json-schema-library HOT 3 CLOSED

We were able to solve the issue by calling

const jsonSchema = new JsonSchemaLibrary();
jsonSchema.setSchema(schema);
return getTemplate(jsonSchema, data);

What I have reported may not a bug, but more likely a misunderstanding in the API. I was confused that it only fails when using $ref.

Hi @TimBo93 thank you for the feedback.

For resolution of ids, scopes and references a json-schema has to be compiled before being able to resolve $refs. This is probably not done in the case of getTemplate. You can compile a schema yourself using

import { compileSchema } from "json-schema-library";
const myCompiledSchema = compileSchema(mySchema);

setting the rootschema (which contains the definitions/defs) in the constructor or via setSchema will do this automatically, e.g.

const jsonSchema = new JsonSchemaLibrary(mySchema);

or

const jsonSchema = new JsonSchemaLibrary();
jsonSchema.setSchema(mySchema);

I will update the documentation about this, add the compile command to getTemplate and think about possible api improvements.

Cheers,

Documentation has been updated and latest api changes should prevent some of thise errors.
