OK. This masked the root problem: pm2 logs mm --lines 100 doesn’t show the same information as npm run start. From pm2 logs:

Once I discovered that node-fetch wasn’t found it was easy enough to follow your instructions to do an npm install node-fetch, although if I ran it in the MMM-Remote-Control directory I got

pi@magicmirror:~/MagicMirror/modules/MMM-Remote-Control $ npm install node-fetch

up to date, audited 88 packages in 4s

But from the MM directory:

pi@magicmirror:~/MagicMirror $ npm install node-fetch

added 6 packages in 17s

And which 6 packages got installed? Who knows. At any rate, Remote-Control API’s are now working again for me. Looking at the MM changelog again I see in the Updates section “Replace node-fetch with internal fetch (#2649) and remove digest-fetch.” To me that seems to be a transparent change that should break anything.

And a question for you, Sam. When you installed MMM-Remote-Control in V2.25, did you have to run npm install node-fetch? If not, why not?

Excellent. Then I’ve got some problem in my Pi environment. Thanks for the info and taking the time to try to duplicate the issue.

Yeah, secureEndpoints made no difference for me. What’s your MM host, a Raspberry Pi? If so, are you running bullseye? And you’re running MM V2.25, right?

Thanks! I’ll try using an apikey. That’s a difference between your configuration and mine.

@sdetweil
And if I post, please read it and think about what you are about to post before adding noise to the discussion. I am not seeing any error messages about missing modules and I am not getting a black screen.

Perhaps you could load Remote-Control and let me know if you can duplicate my problem?

@sdetweil
I posted the startup section of the log file. You can see there are no error messages about missing modules. It seems you’re trying to suggest solutions to all the problems similar to this one that have been covered before. I appreciate that but I did research this problem before posting here.

Have you updated your MM to V2.25 and tried to access the Remote-Control API? Does it work for you?

@sdetweil

No difference.

let config = {

              // - "localhost", 	// Address to listen on, can be:

Hi, all. Magic Mirror and Remote-Control had been working great on my Raspberry Pi (bullseye). After updating to V2.25.0 (which required updating nodejs from version 16 to 18), none of the /api functions or /remote.html provided by Remote-Control are working. MM is accessible at http://192.168.249.34:8080.

There are no suspicious error messages in the logs after making the http request and nothing unusual in the startup:

I’ve tried removing and re-installing the module according to the instructions but the problem remains. Any help would be appreciated.
