Error small micro-channel readFile: fail parameter error: parameter.filePath should be String instead of Undefined;

I am of the problems encountered when using the camera assembly

The reason is not to save the file path (after the micro-channel will use the camera to take pictures of images saved in a temporary path, so you need to define a variable to store this path, the next use of the variable to access the file)

So variable with the file you need to access / temporary file src, before the next visit.
