❌ Actual Behavior

1 validation error for TiDBVectorConfig Value error, config TIDB_VECTOR_HOST is required [type=value_error, input_value={'host': None, 'port': 40...ame': 'langgenius/dify'}, input_type=dict] For further information visit https://errors.pydantic.dev/2.8/v/value_error

To resolve the validation error requiring TIDB_VECTOR_HOST when trying to use the Tencent vector database with Dify version 0.6.15, ensure that the configuration for the Tencent vector database is correctly set in your .env file. Here is an example configuration:

# Vector database configuration
VECTOR_STORE=tencent

# Tencent vector database configuration
TENCENT_VECTOR_DB_URL=http://10.1.10.34
TENCENT_VECTOR_DB_API_KEY=dify
TENCENT_VECTOR_DB_TIMEOUT=30
TENCENT_VECTOR_DB_USERNAME=dify
TENCENT_VECTOR_DB_PASSWORD=dify
TENCENT_VECTOR_DB_SHARD=1
TENCENT_VECTOR_DB_REPLICAS=2

Make sure to set the VECTOR_STORE variable to tencent and provide the necessary configuration parameters for the Tencent vector database. This should bypass the need for TIDB_VECTOR_HOST and other TiDB-specific configurations ^[1][2].
