Question

Warning: found unsupported runtime 'nodejs18.x' for function 'rs-ms-v1'
× Unsupported runtime

we are using serverless.yml file

my serverless library version is 3.33.0 i checked the aws documentation lambda functions started to support nodejs18.x

please attach your solutions below .

Answer 1

Nodejs18.x has been supported since version 3.25.0, so there are a couple things to check:

1. Inside your project directory, run serverless --version to ensure that you're not overriding a global installation of serverless framework with an older one inside the project.
2. Double check any plugins you're using to verify this error is not being returned by a plugin. It sounds like you may be running a local emulator to execute your function (like serverless-offline), which also may need to be updated.
3. Share logs from CloudWatch if this problem persists.

Answer 2

so i found the answer so i updated the serverless library but i did not updated the serverless-offline library , due to that we are getting this error. latest serverless versions are supporting nodejs18.x .in order to use serverless please update all the packages related to serverless .

Answer 3

1. Upgrade the serverless CLI

curl -o- -L https://slss.io/install | bash
# validate
sls --version

2. uninstall & re-install last version of serverless-offline

npm uninstall serverless-offline --save-dev
npm i serverless-offline --save-dev
