Fcitx5 on weston fsl-imx-xwayland

[LuThaiHoc]

Hi. Im trying to use fcitx5 on weston wayland.
When building image via Yocto, I follow this link to build fcitx5 input method and its engines: https://github.com/ashie/meta-inputmethod
The built was successed, but I cannot type any specical language.
My configuration:
weston.ini:

[input-method]
path=/usr/bin/fcitx5

/etc/environment

export XMODIFIERS=@im=fcitx
export GTK_IM_MODULE=fcitx
export QT_IM_MODULE=fcitx

~/.config/fcitx5/profile (auto generated)

Result of fcitx5-diagnose:
diagnose.txt

I see that fcitx5-remote always result 0 although I tried to active input method via -o options
Can someone help me to debug this? Thank you!
