Validation for array returns error for only 1st item and ignores other errors

Hi, I am using schema-validation with express-validator 4.3.0, using a jsonSchema.json file. Within the schema, there is an array of objects. express-validator returns an error if only the 1st object value is incorrect. If other objects i.e 2nd onwards (index : 1 ) has incorrect values, it does not return errors.

Using code as :

  req.checkBody(jsonSchema);
  return req.asyncValidationErrors();

eg: jsonSchema

 {
"property1":  {
    "optional": true
  },
  "propertytest.*": {
    "isURL": true
  }
}

Data:

{
"property1":  {
  "test":"testvalue"
},
"propertytest": [
   "http://sldjfsdjf.sldfjsdf.com/sdlfjskd",
    "test"
]
}

I have looked at the code and it seems this is because in express_validator.js: following code picks up only the first value from selectFields() as selectFields(req, context)[0]

return function(req, res, next) {
    const contexts = [];
    function runContexts() {
      contexts.filter(context => !context.promise).forEach(context => {
        const field = selectFields(req, context)[0];

Can you please let me know if there is a workaround for this and an example of it.
