I confirm that this is a problem I’m also seeing in the latest firmware (0.63.3).
Can you please send the file that causes that message?
I’m seeing the same behaviour. Is there an issue/ticket number that you can give us so we don’t have to nag you about it? Thanks and kind regards!
Not at the moment, you can create an issue on github
Actually, somebody else had already created one: https://github.com/flipperdevices/flipperzero-firmware/issues/1549
No, that’s about NFC-A files, not Mifare DESFire
That’s also not it, this is actually a duplicate of the issue you’ve posted above
I’m having the same issue.
I have excactly the same issue with tesla sub files . on 0.65.2
The issue there is with the files, not the firmware.

any chance that you can share a sample tesla file test ?
This should at least open on flipper…
thanks , this is exactly the one who are giving the error message 
ALL of those open fine on my flipper …
Maybe it’s some sort of restriction of frequency of your region ?
Maybe damaged files ? Damaged SD ? Check integrity of your files and if they were properly downloaded … Also check file system of your SD…
Hey hello.
Regarding the Tesla files:
I don’t know if this have been mentioned previously in the thread but when you download the files from GitHub make sure you download the “raw” file (click “raw”) and then ctrl-s and save the file to your computer.
When you have the file on your computer make sure that your Windows does not hide file extensions (view tab then file extensions must be ticked in explorer).
I had this issue and got the can’t parse-error and it turns out the files had .sub.txt ending but Windows was hiding the .txt-ending so the files didn’t parse.

Any news on this? Having exactly the same issue…
Me too I made the script for proxmark json to NFC flipper and i get the same error., any solution?
I’m having the same issue. With some of the cards, only UID is being copied and it only shows the option to emulate the UID and not the info. How does one fix this?
