Troubleshooting Guide: Receive updates when a new account is added by an admin in ActiveCampaign

Common Issues & Solutions

1. Workflow Won't Start

Issue: No trigger activation

Symptoms: Workflow doesn't execute automatically Solutions:

Check if workflow is active
Verify trigger configuration
Test trigger manually
Check webhook URL accessibility

Issue: Credential errors

Symptoms: Nodes fail with authentication errors Solutions:

Verify credentials are properly configured
Check credential expiration
Test credentials independently
Update credential values if needed

2. Node Execution Failures

Issue: HTTP Request failures

Symptoms: HTTP nodes return error codes Solutions:

Check URL accessibility
Verify request format
Check authentication headers
Review rate limiting

Issue: Data format errors

Symptoms: Nodes fail with parsing errors Solutions:

Verify input data format
Check data transformations
Validate JSON structure
Use data validation nodes

Issue: API rate limiting

Symptoms: External API calls fail with rate limit errors Solutions:

Implement delay nodes
Use batch processing
Check API quotas
Optimize request frequency

3. Performance Issues

Issue: Slow execution

Symptoms: Workflow takes longer than expected Solutions:

Monitor node execution times
Optimize data transformations
Use parallel processing where possible
Check external service performance

Issue: Memory issues

Symptoms: Workflow fails with memory errors Solutions:

Reduce data volume per execution
Use pagination for large datasets
Optimize data structures
Consider workflow splitting

4. Data Flow Issues

Issue: Missing data

Symptoms: Expected data not available in nodes Solutions:

Check data source connectivity
Verify data filtering logic
Review conditional nodes
Check data mapping

Issue: Incorrect data format

Symptoms: Data doesn't match expected format Solutions:

Add data validation nodes
Check data transformations
Verify API response format
Use data type conversion

Debugging Techniques

1. Enable Debug Mode

Go to n8n Settings > Logging
Enable debug mode
Review detailed execution logs
Check node-specific error messages

2. Test Individual Nodes

Run nodes in isolation
Use sample data for testing
Verify node configurations
Check input/output formats

3. Use Execution History

Review past executions
Compare successful vs failed runs
Check execution data
Identify patterns in failures

4. Monitor External Services

Check API status pages
Verify service availability
Monitor response times
Check error rates

Error Codes Reference

HTTP Status Codes

400: Bad Request - Check request format
401: Unauthorized - Verify credentials
403: Forbidden - Check permissions
404: Not Found - Verify URL/endpoint
429: Too Many Requests - Implement rate limiting
500: Internal Server Error - Check external service

n8n Specific Errors

Credential Error: Authentication issue
Data Error: Format or validation issue
Connection Error: Network or service unavailable
Execution Error: Node configuration issue

Prevention Strategies

1. Proactive Monitoring

Set up execution monitoring
Configure error alerts
Monitor performance metrics
Track usage patterns

2. Regular Maintenance

Update credentials regularly
Review and test workflows
Monitor for deprecated features
Keep documentation current

3. Testing Procedures

Test with various data scenarios
Verify error handling
Check edge cases
Validate recovery procedures

4. Documentation

Keep troubleshooting guides updated
Document known issues
Record solutions for common problems
Maintain change logs
