What should I say. Now the MMM is running.

But now I have on my second mirror another problem. I will open a new post for it.

Thank you all for your help :-)

this makes it a single line comment and the next line becomes active

in a diff, red is old, green is new

language: "de",

and I changed the node.helper as @sdetweil had advised

Because the colours of the result could be important, I have also included a screenshot as an attachment.

in the module folder do

git diff

to see the changes

When I change the line 63 I got the following error when I start my MMM

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 1)

I checked the line a few times to make sure I hadn’t mistyped it.

do this
cd to the module folder
nano node_helper.js

change line 63 from

ERROR ** " + error);

to
ERROR ** " + response.statusCode);

then rerun MagicMirror and look at the stdout content in the pm2 logs
