@MichaelYangjson Hello there! I'm a bot that can help you solve bugs, answer questions, and become a contributor. I'm here to help you while waiting for a human maintainer.

To resolve the "database name param not found" error when migrating a vector to Tencent Vector DB using Dify version 0.6.12, self-hosted via Docker, ensure that the TENCENT_VECTOR_DB_DATABASE environment variable is set correctly in your .env file.

Here is the relevant section from the .env.example file:

# tencent vector configurations, only available when VECTOR_STORE is `tencent`
TENCENT_VECTOR_DB_URL=http://127.0.0.1
TENCENT_VECTOR_DB_API_KEY=dify
TENCENT_VECTOR_DB_TIMEOUT=30
TENCENT_VECTOR_DB_USERNAME=dify
TENCENT_VECTOR_DB_DATABASE=dify
TENCENT_VECTOR_DB_SHARD=1
TENCENT_VECTOR_DB_REPLICAS=2

Make sure that TENCENT_VECTOR_DB_DATABASE is set to the correct database name. If it is not set or is incorrect, you will encounter the "database name param not found" error.

Additionally, ensure that the TencentConfig class in your code correctly maps the environment variables to the configuration parameters. The database parameter should be properly passed to the VectorDBClient initialization. Here is the relevant part of the code:

class TencentConfig(BaseModel):
    url: str
    api_key: Optional[str]
    timeout: float = 30
    username: Optional[str]
    database: Optional[str]
    index_type: str = "HNSW"
    metric_type: str = "L2"
    shard: int = 1,
    replicas: int = 2,

    def to_tencent_params(self):
        return {
            'url': self.url,
            'username': self.username,
            'key': self.api_key,
            'timeout': self.timeout
        }

Ensure that the database parameter is correctly set and used in the _init_database method:

def _init_database(self):
    exists = False
    for db in self._client.list_databases():
        if db.database_name == self._client_config.database:
            exists = True
            break
    if exists:
        return self._client.database(self._client_config.database)
    else:
        return self._client.create_database(database_name=self._client_config.database)

By verifying these configurations and ensuring the correct environment variables are set, you should be able to resolve the "database name param not found" error ^[1][2][3].
