HTTP PUT image to 2N intercom

Ok, tried that now, new error.

Code:

09.02.2023 06:25:54
User script:19: invalid value (nil) at index 5 in table for 'concat'
stack traceback:
[C]: in function 'concat'

I'm suspecting that either the path to the file is wrong or there's a permission missing somewhere.
I've tried using /img/FILE and /data/ftp/img/FILE
