Cannot read property 'defaultEncoding'

[mbilalg]

I had installed the plugin by following command in serverless 2.53.1.

npm install --save-dev serverless-s3-sync

After installing I had imported the plugin like this in serverless.yml

plugins:

• serverless-plugin-common-excludes
• serverless-plugin-include-dependencies
• serverless-python-requirements
• serverless-s3-sync

But (serverless deploy) is giving the following error. Screenshot of error is also attached. (This error only happens when I import this plugin of serverless-s3-sync in serverless.yml file).

ERROR DETAILS: TypeError: Cannot read property 'defaultEncoding' of undefined at _write (node:internal/streams/writable:291:24) at WriteStream.Writable.write (node:internal/streams/writable:334:10) at NodejsStreamOutputAdapter.ondata (C:\serverless_v2\node_modules\readable-stream\lib_stream_readable.js:619:20) at NodejsStreamOutputAdapter.emit (node:events:394:28)

I'm facing same problem ... could you fix it ?

It's probably realted to the version of graceful-fs. The dependency @auth0/s3@1.0.0 of this plugin uses an old version (4.1.5) and the other plugins use graceful-fs@^4.2.0. This mismatch could lead to the problem.

Anyone else that runs into this, seems to be a conflict between

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

To fix it, I tweaked package.json to pin the underlying dependency to 4.2.8 and make this work.

... "resolutions": { "graceful-fs": "4.2.8" }, "scripts": { "test": "none", "preinstall": "npx npm-force-resolutions" }, ...
