YAML input in trigger UI

[sharanroongta]

Description

I work in a project where having a yaml input in the web UI (instead of json -> which is in the case of object type param) is beneficial.

I understand that airflow support multiple datatypes - ints, strings, list/arrays, and objects.
Is it possible to also have yaml as a input.

On a sidenote: I thought of interpreting multiline input, i.e., list of strings as my input, which I can join and interpret as yaml.
However, airflow tends to remove trailing white spaces in string list items, thereby losing indentation information.
example:

a multiline array input of

a:
    b: c

is incorrectly transformed to yaml of this form:

{a: None, b: c}

instead of:

{a: {b: c}}

is this the intended purpose or is this is a bug??

Use case/motivation

I would like a human readable input, where the user can copy paste their yaml files in a text box.
