Run aws lambda invoke --function-name smt-lambda-function --cli-binary-format raw-in-base64-out --payload '{"key1": "value1", "key2": "value2", "key3": "value3" }' --region ap-southeast-2 response.json

Get error

usage: aws [options] <command> <subcommand> [<subcommand> ...] [parameters]
To see help text, you can run:

  aws help
  aws <command> help
  aws <command> <subcommand> help

Unknown options: --cli-binary-format, response.json

[sunmingtao]

Getting rid of --cli-binary-format raw-in-base64-out works

aws lambda invoke --function-name smt-lambda-function --payload '{"key1": "value1", "key2": "value2", "key3": "value3" }' --region ap-southeast-2 response.json

Turns out --cli-binary-format is only supported in CLI version 2

[sunmingtao]

To uninstall AWS-CLI version 1:

pip3 uninstall awscli -y

Then install aws-cli version 2 Download from https://awscli.amazonaws.com/AWSCLIV2.pkg and double click to install Open a new terminal window aws --version

To invoke the lambda function asynchronously , aws lambda invoke --function-name smt-lambda-function --cli-binary-format raw-in-base64-out --payload '{"key1": "value1", "key2": "value2", "key3": "value3" }' --invocation-type Event --region ap-southeast-2 response.json
