TM-m30II-NT usb Base64 image @ IOS - NSInvalidArgumentException #111

Hello!

I am trying to send the printer an image via USB.

I get the following error:

NSInvalidArgumentException: *** -[NSURL URLByAppendingPathComponent:]: component, components, or pathExtension cannot be nil.

device properly discovered and initialized

{
printer: {
bt: , 
ip: , 
mac: , 
name: TM-m30II-NT, 
target: USB:583939500274300000, 
usb: 583939500274300000
}
}

but once I sent the printing commands:

printing
        .initialize()
        .align("center")
        .newline()
        .image({ uri: image }, { width: this.options.adapter.escWidth })
        .newline()
        .cut()
        .send();

I get the error above

I checked i am sending a proper base64 string like in the example and the docs "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAjoA ... " (189512 length)

I tried also to pass a temporary file as URL for URI / require it but it didn't worked because cannot transform requires on runtime

any suggestions?

working with iPad Air 5gen ios 16.5

Thanks!!
