Identical URL Observables can still be added multiple times to the same case

[Passimist]

Reopen of issue at the bottom of this post:

@To-om @nadouani Hi guys, I hope you had a nice start into the new year! Can you please reopen this issue?
I just upgraded to TheHive 4.0.3 and I can still upload identical url observables via TheHive4py (not the latest thehive4py version but the one before EDIT tried it with the newest thehive4py version and issue occurrs there aswell).


If I can provide any additional information to help fix this please let me know.
Some information that may help:
Submitted via thehive4py
Submitted almost at the same time
Observables have different observable IDs
This does not always work (but quite often as far as I can tell)
EDIT: As a workaround I now use a filelock to prevent simulaneous creation of identical URL observables. So far this helped preventing the bug. If this is a fix then it might be some kind of race condition? I ll update if the problem occurrs with this workaround in the next few days.

Great, let me know if you need any information! Since I prevented simultaneous URL observable creation in my code that uses thehive4py (with a file lock and 5sec sleep after claiming the lock) the issue did not occurr again.

This issue is already fixed in 4.1.0
