Optimizing/reviewing large chunks of code fails with "Improperly formed request"

[Furytron]

Describe the bug

Apologies if this is logged before or not specifically an Amazon Q Eclipse issue, but I couldnt find information on it. When sending code to prompt, or using inline options on large chunks of code (246 loc in my case) and asking Q to review or optimize will throw an error.

To Reproduce

1. Select a whole Java class
2. Send it to the prompt or right click and select inline optimize
3. See failure:

An error occurred while processing your request.
Details: org.eclipse.lsp4j.jsonrpc.ResponseErrorException: Improperly formed request.

Expected behavior

I would expect it to review/optimize the code, or produce a user friendly error. If there is a problem in formatting, or length of code, it should warn me instead of failing. I've no idea what the problem is.

Screenshots

Your Environment:

• OS: Windows 11
• Eclipse IDE for Java Developers (includes Incubating components)
• Version: 2024-06 (4.32.0)
• Build id: 20240606-1231
• Amazon Q for Eclipse plugin version: Amazon Q 1.0 (Pro)
• JVM version: OpenJDK Runtime Environment Temurin-21.0.4+7 (build 21.0.4+7-LTS)

Additional context

• It seems similar to this issue: Amazon Q chat raise an issue when asking anything (Improperly formed request) aws-toolkit-jetbrains#4114
• Amazon Q signs me out, and asks me to reauthenticate so often that I've definitely done this.
• Restarted Eclipse and made sure to update the Amazon Q extension
