connect-redis: SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode

Hello.

I’ve installed the last version - 3.4.0 - and it’s giving me the following error:

/Users/user/dir/project/node_modules/connect-redis/node_modules/debug/src/node.js:132
	let val = process.env[key];
	^^^

What I’ve done for now was a downgrade to at least 3.2.0 to get it resolved.

Inside your main app .js file, where you have require('connect-redis')() put use strict at the very top, the first line of code.

I updated node to v11.6.0

Latest version of node is currently 12.1.0

nvm install 12.1.0
nvm use 12.1.0
nvm alias default 12.1.0

Inside your code, where you have require(‘connect-redis’)(), insert this as the first line of code… use strict

@knoxcard @wavded I started a project from scratch just to make sure and it’s working fine, so I think the problem is related to the project I was working on before. Sorry for any inconvenience and thank you for your support.
