Pre-process RJSF ui:schema to resolve references

  for (let k of Object.keys(object)) {
    const v = object[k]
    if (v === null) {

      continue
    }

      if (v.$ref && v.$ref.startsWith('#/definitions/')) {
        const k = v.$ref.substr(14)
        if (definitions[k]) {
          delete v.$ref
          Object.entries(definitions[k]).forEach(([k, v1]) => { v[k] = v1 })
        }
      } else {
        traverse(v, definitions)
      }
    }
  }

export function resolveUiSchemaReferences(input) {
  let { definitions, ...schema } = input
  schema = cloneDeep(schema)
  if (typeof definitions === 'object') {
    traverse(schema, definitions)

  return schema

Thanks, but does not work if you use $ref in the definitions themselves... :)
This works but I guess this is not really clean :

if (typeof $defs === 'object'){
  //replace $ref within the definitions theirselves
  $defs = cloneDeep($defs);
  traverse($defs,$defs);

  //replace $ref within the schema
  schema = cloneDeep(schema);
  traverse(schema, $defs)
}

Maybe that this tool is better ?
But I can't get it working in my React app.
