Same here.

What is your version of the socket.io-adapter package? It should be 2.5.4, isn't that the case?

See:

socket.io-redis-adapter/package.json

Lines 27 to 29 in cdb5535

	"peerDependencies": {
	"socket.io-adapter": "^2.5.4"
	},

Specifying the peerDependencies seems to solve the issue on my side, not sure why pnpm prefers installing 2.5.2 though

Delete yarn.lock then yarn install again fix the issue.
