System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: GeForce MX230/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 442.23

Blender Version
Broken: version: 2.90.0 Alpha, branch: master, commit date: 2020-07-11 18:41, hash: ee5c2f6ead
Broken: version: 2.90.0 Beta, branch: master, commit date: 2020-07-25 11:30, hash: a8d058dbf4
Worked: None

Short description of error
I am not sure if this is a bug or a limitation, but inserting a key frame on a field weight in mantaflow results in this error:
Could not insert keyframe, as RNA path is invalid for the given ID (ID = OBCube, path = modifiers["Fluid"].settings.effector_weights.gravity)

I can animate field weights in other physics systems, only mantaflow has this issue

Exact steps for others to reproduce the error
Open blender
Add a domain or quick fluid to an object
Press I hovering over a field weight

Blender build updates everyday.
Need use latest build, before creating any bug report.

I have tested on latest builds before making the report, its the same in the 2.90 builds
