Compilation fails if property name is start (substring) of another property #525

Is there an existing issue for this?

Describe the issue

I faced a very strange bug (I think). I have two classes, OrderDto and Order. These classes have 2 properties (among others), of which one is a starting substring of the other: shippingFee and shippingFeePerPallet, both nullable numbers.
I have a mapping profile to map from the former to the latter. First, I didn't specify these in the mapping profile explicitely, but when I tried to build the project, it failed with the following error (at the addProfile function):

.../server/node_modules/@automapper/core/index.cjs:1092
  return Object.prototype.hasOwnProperty.call(obj, property);
                                         ^
[2022.12.19 10:44:47] [error] -  TypeError: Cannot convert undefined or null to object

[...]

at addProfile (.../server/node_modules/@automapper/core/index.cjs:1373:11)

I narrowed down the problem to the shippingFee property. I tried adding both properties to the profile explicitely, as follows:

createMap(
    mapper,
    OrderDto,
    Order,
    forMember(
      (dest) => dest.shippingFee,
      mapFrom((source) => source.shippingFee)
    ),
    forMember(
      (dest) => dest.shippingFeePerPallet,
      mapFrom((source) => source.shippingFeePerPallet)
    )
  );

But it still doesn't work. The way I got it working is that I deleted shippingFee from both the profile and the OrderDto class (not a good solution, but it confirms the source of the issue). Another workaround was that I renamed shippingFee to shipiingFee (yes, with a typo) in both classes, in which case it magically worked.

The strange thing is, that other properties also have this kind of same-starting-substring, but they work without errors (like status and statusEn) - even the workaround has the same substring: shipiingFee and shippingFeePerPallet also start with "ship".

Models/DTOs/VMs

export class OrderDto {
...
  @AutoMap() @Expose() shippingFee?: number;
  @AutoMap() @Expose() shippingFeePerPallet?: number;
...
}

export class Order {
...
  @AutoMap() @Expose() shippingFee?: number;
  @AutoMap() @Expose() shippingFeePerPallet?: number;
...
}

Mapping configuration

createMap(
    mapper,
    OrderDto,
    Order,
    forMember(
      (dest) => dest.shippingFee,
      mapFrom((source) => source.shippingFee)
    ),
    forMember(
      (dest) => dest.shippingFeePerPallet,
      mapFrom((source) => source.shippingFeePerPallet)
    )
  );

Steps to reproduce

1. Implement the following classes and mapping
2. Add the profile
3. Try to build

Expected behavior

Should map the properties to their counterparts as expected.
