Hey @timkley,

Thanks for reporting this one, I have just taken a quick look and it looks like we updated the html editor a while back and forgot to remove the expression option from that node.

You can now just input expressions directly into that field and they will just work without having to select an expression. I have created NODE-1298 to remove the expression toggle on the field and to add a note to let users know.

Hi @Joffcom,

I've only tried setting it to expression because JavaScript was not interpreted, see the screenshots:

I've also tried updating N8N to the latest version to see if it's an issue with v1.34.2, but it seems like the docker registry doesn't have the most up to date version.

Hey @timkley,

That is interesting, I guess there is a bit more to do there I will update the ticket. Docker does have the newest release but the latest tag is not the actual latest release we use 2 tags latest and next with next being slightly newer. We tend to change the labels once a week once we are confident the release is ok.

Thank you for the explanation and updating the ticket! :)
