why do I get an error 'invalid arithmetic oper

问题:

I am trying to parse yaml to Json. and I'd like to set the array that has string index.

when I v tried it I got an error

here is my source and error

keys=$(echo $ci_json | jq 'keys')
key_array=($keys)
ARR=()

for raw_key in ${key_array[@]}; do
        if [ $raw_key = '[' -o $raw_key = ']' ]; then
                continue;
        else
                key=$(echo $raw_key | sed -e 's/"//g' -e 's/,//g')
                value=$(echo $ci_json | jq .$key)$'\t'
                ARR[$key]=$value
        fi
done

Error : localhost.localdomain: syntax error: invalid arithmetic operator (error token is ".localdomain")

This error appeared at "ARR[$key]=$value"

anybody helps me?

 Error : localhost.localdomain: syntax error: invalid arithmetic operator (error token is ".localdomain")

This happens on ARR[$key]=... when ARR is an indexed array (not associative) and the value of key is localhost.localdomain. Indexed arrays should use numeric subscripts, not arbitrary strings.

If you want to use string indexes with ARR, you must declare it as an associative array, which is supported as of Bash 4:

declare -A ARR

If you want to use non-numeric keys, use an associative array instead of a normal array. You have to declare it, though, so replace

ARR=()

with

declare -A ARR
