What did you do?
v -g -o vdbg cmd/v && vdbg bug_fixed_array_json2.v

import x.json2
struct Pos { pos [3]f64 }
input := '{"pos": [0.5, 0.0, 0.5]}'
p := json2.decode[Pos](input)!
dump(p)

What did you expect to see?

the pos field should be: pos: [0.5, 0.0, 0.5]

What did you see instead?

[bug_fixed_array_json2.v:5] p: Pos{
    pos: [0.0, 0.0, 0.0]
}

The equivalent program, using json works:

import json
struct Pos { pos [3]f64 }
input := '{"pos": [0.5, 0.0, 0.5]}'
p := json.decode(Pos, input)!
dump(p)

producing:

[bug_fixed_array_json_working.v:5] p: Pos{
    pos: [0.5, 0.0, 0.5]
}

x.json2 also cannot decode a struct with an int slice.

import x.json2
struct Pos { pos []int }
input := '{"pos": [1, 3, 5]}'
p := json2.decode[Pos](input)!
dump(p)

producing:

v run file.v                                                                                                                                                       ─╯
[file.v:5] p: Pos{
    pos: []
}
