Bug when previewing an ascii file whose mimetype is not detected

[santilin]

This is to report a bug in the code.

On fileinput.js, line 448 there is the getMimeType() function which has as its firs parameter signature.

This function is called on line 5788 with the hex variable as first parameter, but hex is not defined.

The problem arises when the plugins must show a preview of an ASCII file whose mime type is not detected, like a composer.lck file. In this case, an error is logged to the console signature not defined and the file is not shown in the preview window.

I have the exact same issue with a png image.

filetype is loaded with cdn in the order the documentation states.

<script defer src="https://cdn.jsdelivr.net/gh/kartik-v/bootstrap-fileinput@5.5.0/js/plugins/buffer.min.js" type="text/javascript"></script>
            <script defer src="https://cdn.jsdelivr.net/gh/kartik-v/bootstrap-fileinput@5.5.0/js/plugins/filetype.min.js" type="text/javascript"></script>
            <script defer src="https://cdn.jsdelivr.net/gh/kartik-v/bootstrap-fileinput@5.5.0/js/plugins/sortable.min.js" type="text/javascript"></script>
            <script defer src="https://cdn.jsdelivr.net/gh/kartik-v/bootstrap-fileinput@5.5.0/js/fileinput.min.js"></script>

The error msg:
Uncaught (in promise) ReferenceError: INT32_BE is not defined
at n (filetype.min.js:11:14534)
at FileTypeParser.parseTokenizer (filetype.min.js:11:14631)

also, when dropping images/files into the container, the console spams size properties

Do not think this is the issue for your use case. The hex variable is defined properly on line 5856 later and is used by the other functions/methods inside reader,onload callback.

Need to verify your issue. Can you share details or a JS FIDDLE to reproduce your issue?

in jsfiddle nothing comes out but it does not load the preview of the file but locally this is the error that marks

Still there is an error in getMimeType().
When trying to upload a .DS2 file (Olympus voice recording), I get an error "Uncaught (in promise) TypeError: signature is undefined" in getMimeType() (line 490 of fileinput.js)
This is very easy to reproduce: download sample DS2 file from https://idictate.com.au/2018/06/download-sample-dss-pro-ds2-audio-files-from-here/ and try to upload it.
