Getting this error when use the s3Sync with python. Followiing is my yaml file.

`provider:
name: aws
runtime: python3.7
region: ${opt:region, 'us-east-1'}

custom:
s3Sync:
- bucketName: abc
localDir: localfiles

functions:
hello:
handler: handler.hello

plugins:

• serverless-python-requirements
• serverless-s3-sync`

Do you have any resolution for this issue?

[alonaddy]

I am getting the same thing :-(

sls s3sync

Does work though ...

[telanniranga]

Since I was not able to get a resolution for this, I used a different approach.

I used this plugin https://www.npmjs.com/package/serverless-scriptable-plugin and that will help you as well. This is more flexible and you can run any command based on serverless events.

Interesting, I ended up using serverless-s3-deploy. Works really well.

hope that helps someone.

I'm facing same problem and since serverless-s3-deploy is not maintained anymore ... could you fix it ?

I did the following steps:

1. Upgrade node to v16.14.0 (it was v14.17.6)
2. remove directory node_modules in the project's directory
3. re install all plugins

And the error just gone.
