How can I use TypeScript and CDK to create a task that prefixes one specific field in the input while leaving the rest unchanged?
Input:
{
"field1": "foo",
"field2": "bar"
}
Desired output:
{
"field1": "baz_foo",
"field2": "bar"
}

An effective method to accomplish this task is by using a Pass function along with the intrinsic feature of States.Format.
const addPrefix = new sfn.Pass(this, 'AddPrefix', {
parameters: {
'field1.$': "States.Format('{}{}', 'baz_', $.field1)",
'field2.$': '$.field2',
},
});
