Hello-Lucy pages are blank

[sinbad339]

I’ve been fighting this issue for several days with a new installation. MMM with Hello-Lucy starts up normally, with several modules displayed. I trigger with HELLO LUCY, then say SHOW PAGE TWO (or any other page I have configured), I hear the “ding”, and I get a blank page. Even with SHOW PAGE ONE, I get a blank page. From there, only SHOW MODULES get me back to an active display.

Here’s what I get from the dev console. The error shown comes from saying SHOW PAGE TWO.

@sinbad339 edit HelloLucy.js

after line 248

} else if (notification === "MODULE_STATUS") {

add a new line and put this on the new line

let self = this

@sdetweil
That worked! Thanks much for the quick reply and the fix.

Being a noob, I probably wouldn’t understand the answer, but why did my basic installation work?

[sdetweil]

@sinbad339 because it didn’t use the function that was broken.
