The correct syntax for using predicates like `P.eq` is to use a string representation in the format `"P.method(value)"`. However, it seems there might be an issue with how the value is being interpreted in your JSON. Here's how you can format your request: ```json { "label": "person", "properties": { "city": "P.eq(\"Hongkong\")" } } ``` Make sure that the entire predicate, including the method and the value, is enclosed in double quotes. If you are still encountering errors, ensure that the JSON is correctly formatted and that the `Content-Type` is set to `application/json` in your request header to avoid any `HTTP 415 Unsupported Media Type` errors <sup>[[1]](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/cn/docs/guides/faq.md)</sup>. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* -- This is an automated message from the Apache Git Service.
