Oct 13, 2025 by talynt.org 132 views

Introduction

Scarlet Discord JDA is a powerful library used for interacting with Discord APIs. However, with the recent update from version 0.4.8 to 0.4.9-rc1, users have been experiencing an error when emitting queries. This error is known as the "Exception emitting query" error, and it's caused by a value being longer than 1024 characters. In this article, we'll delve into the details of this error, its causes, and how to resolve it.

Understanding the Error

The error occurs when the MessageEmbed class in the JDA library tries to create a new field with a value that exceeds the maximum allowed length of 1024 characters. This is a change introduced in the 0.4.9-rc1 version of the library, which is stricter about the length of values in MessageEmbed fields.

Causes of the Error

There are several reasons why this error might occur:

Long field values: If you're using a field value that's longer than 1024 characters, it will cause this error.
Multiple fields with long values: If you have multiple fields with long values, it can also cause this error.
Embedded fields: If you're using embedded fields, which are fields that contain other fields, it can also cause this error.

Resolving the Error

To resolve this error, you'll need to ensure that your field values are within the allowed length of 1024 characters. Here are some steps you can take:

Trim long field values: If you have field values that are longer than 1024 characters, you can trim them to fit within the allowed length.
Use multiple fields: If you have a long field value, you can break it up into multiple fields to avoid exceeding the allowed length.
Use embedded fields carefully: If you're using embedded fields, make sure that the values within the embedded fields are within the allowed length.

Example Code

Here's an example of how you can modify your code to avoid this error:

// Before
MessageEmbed embed = new MessageEmbed();
embed.addField("Long field value", "This is a very long field value that exceeds the allowed length.");

// After
MessageEmbed embed = new MessageEmbed();
embed.addField("Field 1", "This is a short field value.");
embed.addField("Field 2", "This is another short field value.");

Conclusion

The "Exception emitting query" error in Scarlet Discord JDA is caused by a value being longer than 1024 characters. To resolve this error, you'll need to ensure that your field values are within the allowed length. You can do this by trimming long field values, using multiple fields, or using embedded fields carefully. By following these steps, you can avoid this error and ensure that your queries are emitted successfully.

Troubleshooting Tips

Here are some additional troubleshooting tips to help you resolve this error:

Check the length of your field values: Make sure that your field values are within the allowed length of 1024 characters.
Use a debugger: Use a debugger to step through your code and identify where the error is occurring.
Check the JDA library documentation: Check the JDA library documentation to see if there are any specific requirements or restrictions on field values.
