I have tried this on 2 different machines and gotten the same error. Is it something with a newer version of express or some other framework ?

[malcm]

Any idea to solve this issue?

[hgGeorg]

Update connect-mongo to a newer version.

[Magger]

I have got the same problem.

Update connect-mongo to a newer version.

I tried to
npm install connect-mongo
and
npm update connect-mongo
but the problem remains. What shall I try next?

[hgGeorg]

Change the line

"connect-mongo" : "0.4.x"

to

"connect-mongo" : "*"

then run

npm update --save connect-mongo

[Magger]

Change the line
"connect-mongo" : "0.4.x"

to
"connect-mongo" : "*"

In which file?

[Magger]

I have changed the corresponding line in the packages.json file, updated the connect-mongo package and now it seems to work. Thanks.

[lxidea]
