AWS Lambda publish-layer-version, getting: Unknown options: --compatible-architectures, x86_64

I'm trying to create an AWS Lambda Layer using the AWS CLI on Ubuntu, like this:

aws lambda publish-layer-version \
  --layer-name numpy --description "numpy Python 3.9"  \
  --zip-file fileb://./lambda/deps/numpy/python.zip \
  --compatible-runtimes python3.9 \
  --compatible-architectures "x86_64" --output text --query "LayerVersionArn"

But I'm getting this error:

Unknown options: --compatible-architectures, x86_64

I tried all sorts of combinations to no avail. Any ideas?

Solution

  • The root cause was that I had AWS CLI version "aws-cli/2.2.2" installed on my machine...

    As soon as I updated to the latest (version aws-cli/2.4.16), it worked.

    I hope this helps someone in the future.
