@MrPringless did you run
npm install
In the module folder after the git clone?

git clone …
cd MMM-CalDAV
npm install

[MrPringless]

@sdetweil Thanks for your reply.
It’s a bit crazy. I completely reinstalled everything two days ago using copy and paste from the module page.
Then I copied the .env file from the old installation to the new installation.
Could this be because I copied the .env file from a backup into the directory after the reinstallation?
Thanks for the feedback, because I’d like to learn from my mistakes.

@MrPringless I do not know the inner workings of the module.

typically
module not found
means npm install for the module was not done or the package.json for the module didn’t list the library dependency. MMRIZE is very good on that point, so I don’t the second is the reason…

but thanks for the nudge… my backup/restore scripts will save/restore extra files discovered in a modules folder… but files with leading dot are hidden by convention… so I will have to check that

I would not have picked up the .env file… fixed… thx
