Can you please help? thnaks

@bachoo786 Hi, I’m using the module and it’s working. It may be that the “request” module is missing? Have you installed it?
Go the to the module folder and do

npm init

&

npm install request

Let me know if it works.

@snille Hi, trying to use this module but getting below error.

@hedmik Been trying to get it to work for a couple weeks now… no luck for me either… @Snille where you at? LOL

@cowboysdude that error doesn’t line up with the code on GitHub

line 40 col 83 is inside a routine making the url string, not handling a request response

so, what code is actually being run?

[hedmik]

@sdetweil my code looks like this, perhaps it’s a need for an update…?

[sdetweil]

@hedmik well, only the error part at the moment

typically on error there is no body

   error.response.body

I would change that to

  JSON.stringify(error,null,2)

that way u see the whole error object

then, on e we know the error, we can work on the cause

@snille Hi, I’m using this module , and today suddenly magic mirror doesn’t show anymore the pictures from ha sensors (persons). The web interface from a remote computer with chrome works as usual. How can i solve ?
Thanks

[Snille]

@joecas65 Hi! Yes, I do have this issue as well, I have not yet figured out how to solve it. It has to do with the “CORS Policy”. But I’m not sure how to fix it yet. I have to read up a bit and for the moment I’m out of time… Any PR:s would be appreciated! :)

@snille

the cors policies are more restricted with newer chromium releases and therefore in electron too.

There are already some issues here 1, 2 …

If HomeAssistent and mm are running on the same pi this may works when changing the host in the module config to localhost or 127.0.01.

In other cases it will be difficult to access the picture urls from inside the <module-name>.js file, accessing them from the node_helper.js should work. So one solution could be to fetch them with node_helper.js to a mm directory and use these urls in <module-name>.js.

Because I have no HomeAssistant I can not test this so this are only my thoughts so far …
