Ethereum: Transaction reverted: function returned an unexpected amount of data when requesting Institution Data
Ethereum Error: Institution’s data requirement failed with an unexpected amount of data
As a developer working on Ethereum -based projects, it is important to be aware of the potential problems that can arise through Ethereum API. The frequent mistake of developers is the mistake of “transaction laughing” that occurs when an attempt to take action is due to an unexpected transaction result.
In this article, we will check the feature problem that returns an unexpected amount of data to the authorities during the data investigation and will provide measures to prevent and solve the problem.
What does the error mean?
The “transaction supported” error usually occurs if the Ethereum network rejects the customer’s request due to inadequate or invalid position. In this case, the problem is how the API function “authority” returns the data. In particular, the function seems to have returned more data than expected.
Why did my authority fail?
If you request institutional information from the Ethereum Blockchain, you can wait for a simple answer with two or three fields of information (eg account -id, Institute’s name and address). However, the API function seems to return a lot more data that can exceed the expected.
Possible Causes:
There are several possible reasons why this error occurred:
1
Institutional data is not correctly formatted
: “Authority” -Api may have returned the data as a JSON object with additional fields that are returned to an unexpectedly lot of data.
- Network Problems or Overload : The Ethereum network may occur in congestion or problems if transactions fail, leading to a rejected transaction reaction with more data than expected.
3
API restrictions or restrictions : “Authority” may be updated to contain additional fields or features that are not compatible with the client’s application version.
Troubleshooting:
To solve this problem, follow these steps:
- Check the API documentation : Make sure the API function “Authority” is introduced correctly and does not return unexpected data.
- Check Answer : Use a tool like JSON Explorer or Console Protocol to check the answer from the API function. Find signs of excessive or unnecessary data.
3
Test with minimal hopes
: Try to request authority data with minimal expectations (eg only one field) to determine if the problem remains.
- Check Network consistency : Make sure your customer’s application and Ethereum network have no problem such as overload or transaction errors.
Medification Strategies:
If you can reproduce the error on both the local computer and the test network (such as truffle and Ganache), you should introduce the following reduction strategies:
- Insert data filtration : Add logic to filter unnecessary fields from the answer.
- Use page : Return only the first elements of response to reduce the amount of returned data.
If you do these steps, you should be able to eliminate the “transaction back” and successfully request the data of the authority via Ethereum -Api.
Diploma:
“Back” error is a common problem that can be based on interaction with API Ethereum. Understanding the possible causes and implementation of the problems of this error, developers can alleviate the problem and ensure successful data investigation.
