The error message you provided indicates that an exception occurred in the Azure Synapse Analytics connector code while loading data into Synapse. This can happen due to various reasons, such as issues with the table structure, data type compatibility, or connectivity problems. Here are a few steps you can take to troubleshoot and resolve the issue:
-
Verify Table Structure: Double-check the schema and structure of the table you're trying to load data into. Ensure that the column names, data types, and constraints match the data you're attempting to load. Any mismatches can cause errors during the data loading process.
-
Check Data Compatibility: Ensure that the data you're trying to load is compatible with the target table's schema. Verify that the data types, formats, and values align with the expected format in Synapse. Data type mismatches or invalid values can lead to loading errors.
-
Review Connectivity and Permissions: Confirm that the connectivity to the Synapse Analytics instance is established correctly. Ensure that the credentials, network configuration, and firewall rules are properly configured to allow the data loading process. Also, verify that the user or service principal used for the connection has the necessary permissions to perform the data loading operation.
-
Check Synapse Analytics Service Status: Check the status of your Azure Synapse Analytics service to ensure it's running smoothly without any known issues or service disruptions. You can refer to the Azure status page or the Azure Portal for any reported incidents or service interruptions.
