[BUG] DescribeKeyPairs — empty list / HTTP 200 instead of InvalidKeyPair.NotFound

[Leandro-ft]

Service

EC2

AWS API Action

DescribeKeyPairs

AWS Documentation

https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_DescribeKeyPairs.html

https://docs.aws.amazon.com/ec2/latest/devguide/errors-overview.html

If KeyName does not exist → InvalidKeyPair.NotFound (the specified key pair name does not exist).

Expected behavior

aws ec2 describe-key-pairs --key-names does-not-exist

→ error InvalidKeyPair.NotFound, non-zero CLI exit code.

Actual behavior

Floci returns HTTP 200 / CLI exit 0 with empty (or without the requested name):

{
  "KeyPairs": []
}

Impact

Idempotent callers that treat describe-key-pairs --key-names X exit 0 as “present” skip ImportKeyPair / create and leave the account without the key.

Reproduction

export AWS_ACCESS_KEY_ID=test AWS_SECRET_ACCESS_KEY=test AWS_DEFAULT_REGION=us-east-1
export AWS_ENDPOINT_URL=http://localhost:4566

# Fresh / empty account: no key pairs
aws ec2 describe-key-pairs --output json

# Missing name must fail like AWS (InvalidKeyPair.NotFound)
aws ec2 describe-key-pairs \
  --key-names fintree-production \
  --output json
echo "exit=$?"

Environment

• Floci version / image tag: nightly
• Running: Docker (port 4566)

Related

• Many EC2 errors listed in https://docs.aws.amazon.com/ec2/latest/devguide/errors-overview.html are still missing in Floci; the matching describe-by-name/id calls often return HTTP 200 / CLI exit 0 (empty list) instead of the documented fault — same class of bug as this one, not limited to DescribeKeyPairs.
