Ethereum: Transaction reverted: function returned an unexpected amount of data when requesting Institution Data

Ethereum Error: Institution Data Request Failed with Unexpected Amount of Data

As a developer working on Ethereum-based projects, it’s essential to be aware of the potential issues that can arise when using the Ethereum API. One common error encountered by developers is the “Transaction reverted” error, which occurs when an attempt to perform an action fails due to an unexpected transaction result.

In this article, we’ll explore the issue of a function returning an unexpected amount of data during Institution Data requests, and provide steps to troubleshoot and resolve the problem.

What does the error mean?

The “Transaction reverted” error typically occurs when a client request is rejected by the Ethereum network due to an inconsistent or invalid state. In this case, the issue lies in the way the Institution API function returns data. Specifically, it appears that the function has returned more data than expected.

Why did my Institution Data request fail?

When requesting Institution details from the Ethereum blockchain, you might expect a simple response with two or three fields of information (e.g., account ID, institution name, and address). However, in your case, the API function appears to be returning significantly more data, potentially exceeding what’s expected.

Possible Causes:

There are several possible reasons why this error occurred:

• Institution Data is not properly formatted

  : The Institution API might have returned the data as a JSON object with extra fields, causing an unexpected amount of data to be returned.

• Network issues or congestion: The Ethereum network can experience congestion or issues that cause transactions to fail, resulting in a rejected transaction response with more data than expected.

• API limitations or constraints: The Institution API may have been updated to include additional fields or functionality that is not compatible with the version of your client application.

Troubleshooting Steps:

To resolve this issue, follow these steps:

• Check the API documentation: Verify that the Institution API function is implemented correctly and does not return any unexpected data.

• Inspect the response: Use a tool like JSON Explorer or a logging console to inspect the response from the API function. Look for any signs of excessive or unnecessary data.

• Test with minimal expectations: Attempt to request Institution Data with minimal expectations (e.g., only one field) to see if the issue persists.

• Verify network consistency: Ensure that your client application and the Ethereum network are not experiencing issues, such as congestion or transaction failures.

Mitigation Strategies:

If you are able to reproduce the error on both your local machine and a test network (e.g., Truffle, Ganache), consider implementing the following mitigation strategies:

• Implement data filtering: Add logic to filter out unnecessary fields from the response.

• Use pagination: Return only the first few elements of the response to reduce the amount of data being returned.

By taking these steps, you should be able to resolve the “Transaction reverted” error and successfully request Institution Data using the Ethereum API.

Conclusion:

The “Transaction reverted” error is a common issue that can arise when interacting with Ethereum-based APIs. By understanding the potential causes behind this error and implementing troubleshooting steps, developers can mitigate the issue and ensure successful data requests.
