fix: Transform fails if the constructor expects an argument

[pavankris]

Description

https://github.com/typestack/class-transformer/blob/develop/src/TransformOperationExecutor.ts#L160
TargetType is DecimalJS https://github.com/MikeMcl/decimal.js/blob/master/decimal.js#L4285
and the valueType is Decimal
None of the if block in TransformOperationExecutor.ts covers this as a result it falls into
newValue = new (targetType as any)();
and the default constructor expects a valid argument

but if we pass
newValue = new (targetType as any)(value);
everything works

Expected behavior

Why shouldn't the value be passed in constructor ?

@pavankris hi!

Why shouldn't the value be passed in constructor ?

I think because class-transformer doesn't support such case. The reasons might be the follow:

1. It is possible to define anything as a constructor parameter, for example an array: Use plainToInstance() for ES6 object that takes an array as a constructor #1381 (comment)
2. Or constructor might have multiple parameters.

Those two points should tell us, that to support such feature we need to change somehow interface of plainToInstance function, in order to give it a info of how to get constructor parameters and how they should look like.

The issue does not contain a simple reproduction case.

Closing as invalid.
