<!-- Greeting --> 你好，@Wmsdoc！我是一个可以帮助你解决bug、回答问题并成为贡献者的机器人。在等待人类维护者回复的同时，我会尽力帮助你！ <!-- Answer --> I found similar issues related to the error you're encountering: 1. An open issue titled "[Bug] 使用Loader仅导入关系，出现主键是否为空" discusses a similar problem with primary key fields being empty during data import using HugeGraphLoader. Unfortunately, no solution was found in the comments <sup>[[1]](https://github.com/apache/incubator-hugegraph/issues/1986)</sup>. 2. A closed issue titled "Failed to load, cause: The primary keys of the table 'xxx' shouldn't be empty" also addresses a similar error, but again, no solution was provided in the comments <sup>[[2]](https://github.com/apache/incubator-hugegraph/issues/1912)</sup>. Regarding your specific issue, the error message indicates that the primary key fields, specifically `cardNumber`, are not being correctly mapped or are empty. Here are some steps you can take to troubleshoot and resolve this issue: 1. **Check Field Mapping**: Ensure that the `field_mapping` in your `struct.json` correctly maps the CSV fields to the schema properties. For the vertices, make sure that `jykh` and `dskh` are correctly mapped to `cardNumber`. 2. **Verify Data**: Double-check your CSV data to ensure that the `jykh` and `dskh` fields are not empty and contain valid data for all rows. 3. **Primary Key Configuration**: Ensure that the `cardNumber` is correctly set as the primary key in your schema and that it matches the data being imported. 4. **Edge Configuration**: For the edges, ensure that the `source` and `target` fields in your `struct.json` are correctly specified and correspond to the primary key fields of the vertices. 5. **Null Values Handling**: Make sure that your `null_values` configuration in `struct.json` is correctly set to handle any potential null or empty values in your data. By following these steps, you should be able to resolve the issue with importing edge data using HugeGraphLoader. <!-- Dosu Comment Footer --> *To continue talking to [Dosu](https://dosu.dev), mention @dosu.* --- <sup>Help Dosu learn!
