"Could not find MIME for Buffer <null>" on loadFont with fnt file

[KabanFriends]

Expected Behavior

Jimp.loadFont("path/to/fnt/file")

should load the font from a fnt file

Current Behavior

Using jimp.loadFont throws an error about MIME

Failure Information (for bugs)

Error:

I will provide other information if needed. the fnt file I used cannot be shared since it's generated out of a paid font.

is there any solution about this problem？

Is it a bitmap font? that's the only type of font jimp supports right now

I came across this issue. it happened after I converted a file from a ttf format to a fnt format using Hiero and then uploaded it to Firebase storage. It works normally if the file exists locally with my code but once I tried using the uploaded file it gave this error. I uploaded both the fnt file and the png produced when I converted the ttf file.

I also tried downloading the file I uploaded again to test if it still works and it did work when I tested it locally.

Here is a zip file with the original ttf file and the files produced by Hiero. gt-walsheim-pro-bold-20.zip

The issue still persists. No Error const font = await Jimp.loadFont(Jimp.FONT_SANS_128_WHITE);

Exact same error as the title. const font = await Jimp.loadFont( path.resolve( process.cwd(), "src", "assets", "cookie-regular.fnt" ) );

Edit (FIX):

• When I converted the cookie-regular ttf font using this converter it used tga files.
• Jimp doesn't really like the tga files, so I opened them in photoshop and converted them to pngs and saved them.
• Plus, I edited the specifications in the ".fnt" file too so it points to the pngs instead of the tga
• It just started working now so if anyone else is having the same issue follow the steps given above.
