<!-- Answer --> To address the "Undefined vertex label: '?'" error you're encountering in Hubble 1.5.0, it's crucial to ensure that the vertex label '地点' is correctly defined in your graph schema. This error typically occurs if the vertex label hasn't been predefined or there's a mismatch in the label name. Here are the steps to resolve this issue: 1. **Verify Vertex Label Definition**: Make sure the vertex label '地点' is properly defined in your schema. You can use HugeGraph's schema management tools or API to define or check the vertex label. 2. **Check Encoding and Locale Settings**: Ensure your environment supports UTF-8 encoding and, if necessary, set the locale to support Chinese characters (e.g., zh_CN.UTF-8). This is important for Hubble to correctly parse and recognize Chinese characters. 3. **Ensure Compatibility**: Confirm that your Hubble version is compatible with the HugeGraph server. Version mismatches can lead to unexpected errors, including issues with character encoding. 4. **Use Schema Validation Features**: If available, utilize HugeGraph's schema validation to identify any inconsistencies or issues in your graph schema that might be causing errors. For future operations, consider using HugeGraph-Loader for data import tasks, as it supports a wide range of data sources and ensures compatibility with your HugeGraph server. Regularly review your graph schema, check system settings for encoding and locale support, verify compatibility before updates, and monitor logs for potential issues. For detailed steps on schema definition and validation, refer to the HugeGraph documentation and API guides. ## Sources - [hugegraph-hubble/hubble-be/src/main/resources/i18n/messages_zh_CN.properties](https://github.com/apache/incubator-hugegraph-toolchain/blob/master/hugegraph-hubble/hubble-be/src/main/resources/i18n/messages_zh_CN.properties) - [content/cn/docs/quickstart/hugegraph-loader.md](https://github.com/apache/incubator-hugegraph-doc/blob/master/content/cn/docs/quickstart/hugegraph-loader.md) - [hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/HugeGraph.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/HugeGraph.java) - [hugegraph-client/src/test/java/org/apache/hugegraph/api/VertexLabelApiTest.java](https://github.com/apache/incubator-hugegraph-toolchain/blob/master/hugegraph-client/src/test/java/org/apache/hugegraph/api/VertexLabelApiTest.java) - [hugegraph-server/hugegraph-test/src/main/java/org/apache/hugegraph/core/VertexLabelCoreTest.java](https://github.com/apache/incubator-hugegraph/blob/master/hugegraph-server/hugegraph-test/src/main/java/org/apache/hugegraph/core/VertexLabelCoreTest.java) - [hugegraph-loader/src/test/resources/customized_delimiter_in_csv_file/schema.groovy](https://github.com/apache/incubator-hugegraph-toolchain/blob/master/hugegraph-loader/src/test/resources/customized_delimiter_in_csv_file/schema.groovy) - [config.toml](https://github.com/apache/incubator-hugegraph-doc/blob/master/config.toml) <!-- Dosu Comment Footer --> <details> <summary> #### About Dosu </summary> This response is meant to be useful and save you time.
