Hello Guys,

Are you on nest 10?

#

#

Hmm, jest version? And to double check, what does npx nest info print out?

Okay. Then I can only assume that the aws library you're using doesn't support node 12, due to a syntax difference

#

My project uses Snyk to monitor for dependency vulnerabilities as one of the pre-build steps for deployment.
I will have to upgrade this aws dependency to move forward

#

any other solution without upgrading node and nest version ?

#

I'm pretty sure this error comes from invalid node 12 syntax.

#

You could theoretically use Babel to transport node 14+ features bank to node 12 compatible, but that seems very hacky

#

seems upgrading to v14 is the only option
