What's Wrong?

I'm trying to use /login to update an expired AWS Bedrock API key.

When attempting to specify the region as eu-central-1, typing eu-cen cancels the command input.

Typing another region, such as eu-west-1 works without issues. Pasting eu-central-1 as a string works without issues.

What Should Happen?

The TUI should allow me to type eu-central-1 into the input field without cancelling the command.

Steps to Reproduce

  1. Open Claude in a terminal. (in my case, I'm SSHing into an EC2 instance running Amazon Linux 2023)
  2. Run /login.
  3. Choose 3. 3rd-party platform.
  4. Choose 1. Amazon Bedrock.
  5. Choose 2. Bedrock API key (bearer token).
  6. Paste the Bedrock API key, as seen in the attached recording.
  7. The screen will show a Where your Bedrock models are enabled. prompt, as seen in the attached recording.
  8. Type eu-central-1, as seen in the attached recording.

The TUI cancels the request as soon as I type the n key, as seen in the attached recording.

TL;DR

The issue can be worked around by pasting the full region string eu-central-1 instead of typing it manually.

Guidance

  • The problem seems to be related to the autocomplete or input handling in the TUI, specifically when typing eu-central-1.
  • Try typing the region string slowly or paste it as a whole to avoid any potential autocomplete issues.
  • Verify that the issue is specific to the eu-central-1 region by testing other regions with similar naming conventions.
  • Check if the issue persists when using a different terminal or shell to rule out any environment-specific problems.

Example

No code snippet is provided as the issue seems to be related to the TUI input handling.

Notes

The root cause of the issue is unclear, and it may be related to the TUI implementation or the specific environment used. Further investigation is needed to determine the exact cause.

Recommendation

Apply workaround: Paste the full region string eu-central-1 to avoid any potential input handling issues. This is a temporary solution until the root cause is identified and fixed.
