get_fields() not working if some fields has json data

Hello,
i’m not sure if this a bug or i’m making it wrong.

i have some fields like “field_age”, “field_name” and one field “field_json_data” where i store a json string.

When i try to get all fields

$sc = get_fields(42);
var_dump($sc);

it doesn’t work

array(1) {
  ["account_type"]=>
  string(0) ""
}

when i replace the json string with (for example) a number. get_fields() works and returns all fields from my custom post.

This works also

$value = get_field( "field_json_data", 42 );
echo $value;

Is this a bug? If not, is it possible to exlude one field (“field_json_data”) from the get_fields() function?

Thanks in advanced!
Manu

EDIT:
update_field('field_json_data', json_encode($presetPriceList), 42);

Fields with JSON in them should work fine.

Are those the actual field names (starting with field_)? If they are how did you create them?

The word field_ was only an example.
The correct names are json_data, age and name.

// If they are how did you create them?

I enter a name in the Field Label and ACF creates automatically the Field Name.

The Field Type is text.
The value looks like this:
{"route_0":{"from":"Sit","to":"Sot","price":"45$"}}

Did you mean to mark my question as the answer? Sorry, I was wondering about the field names because field names cannot start with ‘field_’ and if they did that could have been a cause of the issue.

For JSON values you could use either a text field or a textarea field with not formatting. Or you could use any type of field that will hold text data and when getting the value set the 3rd parameter in get_field($field, $post_id, $format_value) to false to make sure the value is not formatted or altered in any way.
