Custom Request does not support lists

[rmporsch]

Given we have the following request body:

{
  "instances": [
    {
      "text": "{{ text }}"
    }
    ]
}

The following method is unable to replace "{{ text }}" with the appropriate text.

def find_and_replace_value(obj, value, target='{{ text }}'):
    for k, v in obj.items():
        if v == target:
            obj[k] = value
            return
        if isinstance(v, dict):
            find_and_replace_value(v, value, target)

The proposed changes would address this issue.

As a side question to this PR:

This seems not to be the correct way to do it. Since the value seems to be passed as string if I am not wrong.
So how would I pass a nested dict in the body? Is the value ever serialized?

@Hironsan not sure who the right person for this is but would love to get this merged.
