Error with importing map

[phroureo]

On importing a largeish map from dungeondraft into Foundry VTT (instance hosted on moltenhosting.com))

I receive an error:

Uncaught TypeError: blob is null [Detected 2 packages: dd-import, lib-wrapper]
p - ddimport.js:250
p - ddimport.js:249
_updateObject - ddimport.js:248
_onSubmit - foundry.js:6626

etc. etc.

I can't attach the file here because Github doesn't allow uploads of all file types, but if you'd like me to email it to you please let me know and I can provide it via that method.

How large specifically? I noticed you're using 256 ppi, which is generally entirely overkill

[phroureo]

the map was 70x49 i believe. I think i also tried scaling it down to 100 and still failed.

Well, please verify, as well as try 50 PPI if 100 does not work. 70x49 at 256 is outside the texture size limit of GPUs (and is just ludicrously large in general).
