AppSync Simulator: TypeError

[makka-1]

Describe the bug
Trying to upgrade to serverless framework v3 and its throwing this error

AppSync Simulator: TypeError: Cannot convert undefined or null to object

Its working as expected when I downgrade to v2

I tried the solution mentioned at https://stackoverflow.com/questions/72695038/appsync-simulator-typeerror-cannot-convert-undefined-or-null-to-object and looked at issue #170 too, it didn't solve the issue

sorry for the noise here, I did a fresh installation and this is no longer an issue.
