Fish gives errors when trying to inherit variables

[comfortablynick]

I am running fish 3.0.2 on Arch with the bobthefish theme. When I add your plugin, everything works fine but none of my bobthefish options is preserved. If I set -g async_prompt_inherit_variables 'all', I get the following errors on every prompt:

set: Tried to change the read-only variable “fish_pid”                                                                           
set: Tried to change the read-only variable “hostname”
set: Tried to change the read-only variable “version”
set: Tried to change the read-only variable “fish_pid”
set: Tried to change the read-only variable “hostname”
set: Tried to change the read-only variable “version”

Is there a way to fix this?
