AWS Bedrock "Message":"Authentication failed: Please make sure your API Key is valid."

Description

I had an API key I worked with before expire, and when I started up, I looked at it, went, hmm, I probably need a new one, and did that.

I followed the correct advice to create a new token, add it to my shell, reset the shell and launch opencode, which had updated.

I'm still getting the error with the new token, while

curl -X POST "https://bedrock-runtime.us-east-1.amazonaws.com/model/us.anthropic.claude-sonnet-4-6/converse" \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $AWS_BEARER_TOKEN_BEDROCK" \
  -d '{
    "messages": [{"role": "user", "content": [{"text": "Hello"}]}]
  }'

produces a clear response, implying there's something wrong in opencode itself, NOT my token.
