Thunar warning content type loading failed

I'm running a bash script that collates and organises files before turning it into a zip. When I run the script, multiple Thunar 'warnings' and 'critials' pop that I have a hard time figuring out what they are about (see image). This occurs while the script is copying over files. It mentions a Content type loading error for a strangely named file that I can't place. What generates these warnings? thunar-WARNING **: 16:45:16.720: Content type loading failed for sedVOTg4r: Error when getting information for file /path/to/file/sedVOTg4r : No such file or directory GLib-GIO-CRITICAL **: 16:45:16.722: g_file_info_get_attribute_uint32: assertion 'G_IS_FILE_INFO (info)' failed The script looks as follows:
