Better Handling Of CsvConverter In Inputs

Apr 28, 2025 by ADMIN 42 views

What is the Issue?

If a malformed CSV is configured in a data adapter, it returns no error in the UI, only in the server log there is a very little information. This can be frustrating for users who are trying to troubleshoot the issue. In this article, we will discuss the importance of better handling of errors in CsvConverter and how it can be improved.

Why is Better Error Handling Important?

Better error handling is crucial in any application, especially in data adapters where the input data is critical. In the case of CsvConverter, if the input CSV is malformed, it can lead to incorrect data being processed, which can have serious consequences. Therefore, it is essential to have a robust error handling mechanism in place to alert users of the issue and provide them with sufficient information to troubleshoot and resolve the problem.

Current Issues with CsvConverter

The current implementation of CsvConverter in data adapters has several issues that need to be addressed. Firstly, when a malformed CSV is configured, the UI does not display any error message, leaving users unaware of the issue. Secondly, the server log only provides a cryptic error message, which does not provide enough information for users to troubleshoot the problem.

Requested Improvements

To improve the handling of errors in CsvConverter, the following changes are requested:

Push an alert in the UI: When a malformed CSV is detected, an alert should be pushed to the UI, informing the user of the issue.
Server log improvements: The server log should include the path and filename of the malformed CSV, as well as the name of the lookup adapter. This will provide users with sufficient information to troubleshoot and resolve the problem.

Benefits of Improved Error Handling

Improved error handling in CsvConverter will have several benefits, including:

Better user experience: Users will be informed of the issue and will be able to take corrective action.
Faster troubleshooting: With more detailed error messages, users will be able to troubleshoot and resolve the problem more quickly.
Reduced support requests: Improved error handling will reduce the number of support requests, as users will be able to resolve the issue themselves.

Implementation Plan

To implement the requested improvements, the following steps can be taken:

Modify the UI: Modify the UI to display an error message when a malformed CSV is detected.
Enhance server log: Enhance the server log to include the path and filename of the malformed CSV, as well as the name of the lookup adapter.
Test and validate: Test and validate the changes to ensure that they are working as expected.

Conclusion

In conclusion, better handling of errors in CsvConverter is crucial for providing a good user experience and reducing support requests. By implementing the requested improvements, users will be informed of the issue and will be able to take corrective action. The benefits of improved error handling include a better user experience, faster troubleshooting, and reduced support requests.

Future Development

In the future, the following development can be considered:

Implementing more robust error handling: Implementing more robust error handling mechanisms, as data validation and error checking.
Providing more detailed error messages: Providing more detailed error messages, including the specific error and the steps to resolve it.
Integrating with other tools: Integrating with other tools, such as logging and monitoring tools, to provide a more comprehensive view of the system.
