Common Causes of Error while Uploading Files to Snowflake Managed Internal Stage
Now, let’s explore the common causes of errors while uploading files to Snowflake managed internal stage:
- Invalid File Format: Using an unsupported file format or an incorrect file extension can lead to upload errors.
- File Size Restrictions: Exceeding the maximum file size limit (10GB for Snowflake) can cause upload failures.

Troubleshooting Steps for Error while Uploading Files to Snowflake Managed Internal Stage
Now that we’ve covered the common causes, let’s dive into the step-by-step troubleshooting process:
Step 1: Verify File Format and Size
Ensure that your file is in a supported format (CSV, JSON, or Avro) and within the maximum file size limit (10GB). You can use the following command to check the file size:
ls -lh
If your file exceeds the size limit, consider splitting it into smaller chunks or using Snowflake’s bulk upload feature.
Step 2: Check Authentication and Credentials
Verify that your Snowflake credentials are correct and up-to-date. Ensure that your account is not locked out, and MFA is properly configured. You can use the following command to test your credentials:
snowsql -a -u -p
If you encounter authentication issues, update your credentials or contact your Snowflake administrator.
Step 3: Investigate Network Connectivity Issues
Check your internet connection and firewall settings. Ensure that the Snowflake IP addresses and ports are whitelisted. You can use the following command to test your network connectivity:
ping .snowflakecomputing.com
If you’re experiencing connectivity issues, contact your network administrator or Snowflake support.
Step 4: Check Storage Limitations
Verify that your Snowflake account has sufficient storage capacity. You can use the following command to check your storage usage:
snowsql -a -u -p -q "SHOW STORAGE INTEGRATIONS;"
If you’re near the storage capacity limit, consider upgrading your Snowflake plan or optimizing your data storage.
Step 5: Validate File Integrity and Headers
Check your file for corruption or missing headers. You can use the following command to validate your file:
head -n 1
If your file is corrupted, re-upload or regenerate the file. Ensure that the file headers are correct and well-formed.
Step 6: Review Snowflake Account Configuration
Verify that your Snowflake account settings, roles, and permissions are correctly configured. You can use the following command to check your account configuration:
snowsql -a -u -p -q "SHOW ROLES;"
If you find any configuration issues, update your Snowflake account settings or consult with your Snowflake administrator.
Conclusion
Error while uploading files to Snowflake managed internal stage can be frustrating, but by following these step-by-step troubleshooting steps, you can identify and resolve the underlying issues. Remember to verify file format and size, check authentication and credentials, investigate network connectivity issues, check storage limitations, validate file integrity and headers, and review Snowflake account configuration.
By following these guidelines, you’ll be able to successfully upload your files to Snowflake managed internal stage and continue to leverage the power of Snowflake for your data analytics and warehousing needs.
