there is an b and a ' at the start of the submited string. i hotfixed this by

/lib/python3.6/site-packages/advanced_filters/q_serializer.py def loads(self, string, raw=False): string = string.replace('b'','') string = string.replace(''', '') if self.b64_enabled: d = json.loads(base64.b64decode(string)) else: d = json.loads(string) if raw: return d return self.deserialize(d)

@GegX any luck on this? I am facing the same issue too.

[GegX]

The creater of this lib needs to have a Look at this Code. Or you can try to commit a/this solution. Other then this simple replace I have no clue why this occurs or how to solve this in another way

[rajukumar-rjk]

I think, this issues mainly occur when we give name with sign such as =, ),( etc.. to title when we create advance filter. I avoided that and it started working with my project.

Thanks for the feedback guys, I think I missed the original ticket from May.

@GegX if you could provide reproduction instructions step-by-step, or a failing test, it will make it more clear what is expected vs what is actually happening and we could then fix the issue in the best manner possible.
