override linker,Could not resolve reference to xxx at langium 3.0

[zrwsmd]

i have a outer library function called ADD, by default ,if i refer it at my st file ,it report

so i consider override DefaultLinker$getCandidate to return my custom AstNodeDescription instead of LinkingError,
it works well in langium 1.0 and didn't report Could not resolve reference to StFunction named 'ADD' error

but have some problem in langium 3.0,if i write ADD() without saving(ctrl+s),it work out well but if i press ctrl+s,it stilll report
Could not resolve reference to StFunction named 'ADD'
or another situation,i press ctrl+s,it report this error,but restart vscode extension can also work out well

Can you give a reproducible example? Without it, it's impossible to tell what goes wrong.
