Normal user mount -- log parameter does not take effect

[007Caption]

What happened:
A fatal error occurred when I used an ordinary user to mount juicefs
What you expected to happen:

How to reproduce it (as minimally and precisely as possible):
./juicefs mount -o allow_other --metrics=0.0.0.0:9567 --cache-size=0 --log=.juicefs.log --max-uploads=30 tikv://xxx:2379,xxx:2379,xx:2379/xx /test-bucket/test -subdir=/plat_dmp/buckets/test -d
Anything else we need to know?
When I queried the mount source code, I found that the -- log parameter was not used
