json: cannot unmarshal string into Go struct field preRow.size of type float64

[ERR1R]

Hi, seems i have it working with rabbitmq to insert realtime.. but when i update the size i get this message on the api.

2022/07/27 14:24:52 pre.update

2022/07/27 14:24:52 json: cannot unmarshal string into Go struct field preRow.size of type float64

Im sending with php. I thought maybe i should do something like this:

$size = number_format($size, 2);

			$data = array(
				"id"=> $id,
				"name"=> $release,
				"team"=> $team,
				"cat"=> $cat,
				"genre"=>  $genre,
				"url"=>  $url,
				"size"=> $size,
				"files"=> $files,
				"preAt"=> $timestamp,
			);

but same error.

can you help me to fix this?

You can try strval($size)
