Getting a different error with v3 when running:
sls dynamodb install
TypeError: Cannot convert undefined or null to object

Hello @henhal,

I found a similar issue when running yarn sls dynamodb seed after upgrading to v3. However, if you modify the command to be STAGE={yourStageNameHere} yarn sls dynamodb seed ......., this fixed the issue for me.

Also having provider.stage: ${env:STAGE} set in the serverless.yml will be required.

I hope this helps as I just discovered this now :)
