KeyError: 49796 upon deobfuscating attempt

[tcortega]

Hello, I am receiving an error:

.apk/classes6.dex
Traceback (most recent call last):
  File "/root/deoptfuscator/deoptfuscator.py", line 23, in <module>
    deobfuscator.main(".apk/"+dex)
  File "/root/deoptfuscator/deobfuscator/deobfuscator.py", line 23, in main
    dexfile(dex)
  File "/root/deoptfuscator/deobfuscator/classes.py", line 34, in dexfile
    dexf_a[dex_location+2] = class_dic[f_idx+add]
KeyError: 49796

Do you have any idea on why this might be happening for this specific app? I tried reading the code a bit but couldn't understand much of the logic behind classes.py
