Exception Occurred While Loading Files Not Supported by the Browser

[larvata]

When loading a file the browser cannot parse, e.g., load a HEIC file on windows chrome.

The following line will raise an exception TypeError: Cannot read properties of undefined (reading 'toLowerCase'), because the file.type is empty.
