Hello Kevin!

Can you provide a small reproduction or a stack trace with break on exception turned on? The exception doesn’t originate from the code you’re showing, it’s only being re-thrown there, so the only thing this tells us is that the exception happened in some Uno code invoked from JavaScript, which could basically be anything.

Cheers!

Hi Olle,

the error pops up when running `ImageTools.getBase64FromImage(file).then(function(base64Image) { console.log("The base64 encoded image is \"" + base64Image + "\""); });`

Hey again Kevin,

I’ve created an internal issue on this and we’ll get back to you when we know more. Thanks!

hey olle,

there was a problem the way i was using `ImageTools` now this is fixed `ImageTools.getBase64FromImage({ path: file, name: "Some random name" }).....` the `libc++abi.dylib: terminating with uncaught` has gone as well
