Unsupported OpenType signature <!DO

I am working on klimablomst.tk and using Firebase as hosting, database and storage provider. I have successfully implemented the first two, but I am having some trouble with storage. I am unsure if the problem is server-side or local, though. When I try to load a font in my preload via myFont = loadFont(storage.ref('GreatVibes-Regular.otf').getDownloadURL());, the console spits out this:

Error: "Unsupported OpenType signature <!DO"

​<prototype>: Object { then: then(), "$goog_Thenable": true, ia: (), … } 

Which tells me that Firebase is working just fine, by giving a working URL to the download of the OTF. The error message "Unsupported OpenType signature <!DO" hints at a problem with either the file or Processing. I just don’t get which one. The <!DO comes from my index.html, I don’t know why it thinks that it’s a signature.

The syntax was propably wrong. I am trying this instead:

myFont = storage.ref('GreatVibes-Regular.otf').getDownloadURL().then(loadFont);

@Pyrros – did this solution end up working for you?

No, unfortunately, I just settled with using the respective hyperlinks from my Google Console, which is less than optimal — nonetheless a solution. :slight_smile:
