I3status-rust: How to output json with a script for a custom block

[marvin-steinke]

in the wiki I found the option to create your own custom blocks and also control the state and icons with JSON like this

[[block]] 
block = "custom"
command = "echo '{\"icon\":\"weather_thunder\",\"state\":\"Critical\", \"text\": \"Danger!\"}'"
json = true

Now if I want to output the json with a script e.g.

#!/usr/bin/env bash
echo '{\"icon\":\"weather_thunder\",\"state\":\"Critical\", \"text\": \"Danger!\"}'

and the toml respectively

[[block]] 
block = "custom"
command = "bash scr"
json = true

will result in
Error in block 'custom': Error parsing JSON: EOF while parsing a value at line 1 column 0

How do I parse the JSON correctly?

EDIT:
Without json nothing is being displayed either e.g.

#!/usr/bin/env bash
printf 'test'
#or printf 'test\n' or echo whatever

No error here however no output either.

SOLUTION:
Well apparently I just had to give an absolute path to the script.

I don't use bash but the below works for me:

>./target/debug/i3status-rs testjson.toml                                                          master|22ms|19:58:37

[[block]] 
block = "custom"
command = "fish --command testjson"
json = true

[[block]] 
block = "custom"
command = "echo '{\"icon\":\"weather_thunder\",\"state\":\"Critical\", \"text\": \"Danger!\"}'"
json = true

function testjson
    set val (pikaur --query --sysupgrade --aur 2>/dev/null | wc --lines)
    if test $val -eq 0
        echo "{\"state\": \"Idle\", \"text\": \"AUR $val\"}"
    else
        echo "{\"state\": \"Warning\", \"text\": \"AUR $val\"}"
    end
end

Ah I see. I'll see if I can improve the error message so that it's more obvious why it's failing.

Why can't I use relative paths btw? The script im calling in the example is located in the same directory.

Probably because the shell invoked by i3status-rust has a different working directory to wherever it is that you have stored your script.
