Is there any way I can update a schema to mark a field as required?

Ah, okay. As far as I can tell, it’s not possible. Maybe you could open an issue in the Parse Server repo?

parse-community/parse-server/blob/master/src/Controllers/SchemaController.js#L835


  submittedFields: SchemaFields,
  classLevelPermissions: any,
  indexes: any,
  database: DatabaseController
) {
  return this.getOneSchema(className)
    .then(schema => {
      const existingFields = schema.fields;
      Object.keys(submittedFields).forEach(name => {
        const field = submittedFields[name];
        if (existingFields[name] && field.__op !== 'Delete') {
          throw new Parse.Error(255, `Field ${name} exists, cannot update.`);
        }
        if (!existingFields[name] && field.__op === 'Delete') {
          throw new Parse.Error(255, `Field ${name} does not exist, cannot delete.`);
        }
      });

      delete existingFields._rperm;
      delete existingFields._wperm;
      const newSchema = buildMergedSchemaObject(existingFields, submittedFields);
