Does that help Limitation
It seems it is how PostgreSQL is implemented. Reading the docs:
code :
CREATE OR REPLACE FUNCTION xdecode(data json)
RETURNS TEXT AS
$BODY$
    -- Your implementation here
    SELECT NULL::TEXT;
$BODY$ LANGUAGE SQL;
SELECT xdecode('[1, 2, 3.3, "a", true, null]'::json);
CREATE TABLE foo(
    x INTEGER,
    y FLOAT,
    z TEXT
);

CREATE OR REPLACE FUNCTION xdecode2(data foo)
RETURNS TEXT AS
$BODY$
    SELECT row_to_json(data)::TEXT;
$BODY$ LANGUAGE SQL;
SELECT xdecode2((1, 2.1, 'x'))
CREATE OR REPLACE FUNCTION xdecode3(data RECORD)
RETURNS TEXT AS
$BODY$
    SELECT row_to_json(data)::TEXT;
$BODY$ LANGUAGE SQL;
ERROR: SQL functions cannot have arguments of type record
SQL state: 42P13
CREATE OR REPLACE FUNCTION xdecode4(data anyelement)
RETURNS TEXT AS
$BODY$
    SELECT row_to_json(data)::TEXT;
$BODY$ LANGUAGE SQL;

SELECT xdecode4((1, 2.1, 'x'));
'{"f1":1,"f2":2.1,"f3":"x"}'

code :

may help you . You have two of problems here.
You are not passing cities your LocationList component here, you are passing it as a child. Hence change this:
code :
<LocationList cities={cities} />
const LocationList = ({cities}) => (
    <div>
        {strToComponent({cities})}
    </div>
);
const LocationList = ({cities}) => (
    <div>
        {strToComponent( cities )}
    </div>
);

I hope this helps you . , Why do you want to use DECODE? CASE would seem like a much better fit
