Cannot read property 'singularName' of undefined

When I console.log(allApisSchemas) there seems to be an empty schema:

const validateContentTypesUnicity = apis => {
  const allApisSchemas = Object.values(apis).flatMap(api => Object.values(api.contentTypes));
  **console.log(allApisSchemas)**
  const names = [];
  allApisSchemas.forEach(({ schema }) => {
    //   console.log(Object.keys(schema))
    if (schema.info.singularName) {
      const singularName = _.kebabCase(schema.info.singularName);
      if (names.includes(singularName)) {
        throw new Error(`The singular name "${schema.info.singularName}" should be unique`);
      }
      names.push(singularName);
    }

    if (schema.info.pluralName) {
      const pluralName = _.kebabCase(schema.info.pluralName);
      if (names.includes(pluralName)) {
        throw new Error(`The plural name "${schema.info.pluralName}" should be unique`);
      }
      names.push(pluralName);
    }
  });
};

This appears to be the root of the problem but I can’t see where this empty object is being generated from!
