Upload command!

[Chomikmarkus]

Seems that upload command is not working!
When i issue upload command its freeze agent and seems that agent disconnects as no callbacks is made! From proccess hacker on windows machine i can see that proccess is running but no callbacks made! Command itself does not produce any error output and agent built itself works fine

V2.3-Testing upload.py error output:
[-] atlas ran into an error processing upload:
'File to Upload'

just fixed those two parsing issues, i'll wait for @airzero24 to update the underlying code though

@its-a-feature - I'm facing the below error when I try to upload files(.exe, .txt). Could you help me resolve this? :

-----error-creating task

Hey! I just updated the python files, so you should be able to do sudo ./mythic-cli install github https://github.com/MythicAgents/atlas -f to just pull in the latest (or you can look at the merge i just did from the v2.3 branch to see what i updated).

However, there's an outstanding issue that @airzero24 is aware of that's causing an issue with files in atlas. For some reason, when uploading (or registering an assembly), atlas isn't processing the final success message, so it gets stuck in a weird loop reporting that it's loaded or uploaded an infinite number of times.
