ERROR: Cannot read property 'toString' of undefined

Hi,

Thanks for the wonderful tool. I am getting the below error in “IF” node when I am using “Contains”, but it is working when I select “Equal”.

ERROR: Cannot read property ‘toString’ of undefined

n8n version: 0.66.0

Can you update to the latest version 0.119.0 and see if the error persists?

Could you pls share any upgrade process link as I can’t find it.

Will it impact any of my existing active workflows?

I have found the below command provided by @jan

docker pull n8nio/n8n

Will it impact any of the active workflows?

Hey @nsk!

We had a few breaking changes after version 0.66.0. You can check all the changes that were made here: Changelog | Docs

Once you update your instance, make sure to update your workflows if you have used nodes that have breaking changes.

Thanks. I will check them
