Unable to save certain product properties via Rest API

[cherreman]

Preconditions

1. Magento 2.1.1

Steps to reproduce

1. Create a product via the Rest API, including a price and weight

Expected result

1. The product is saved with the price and weight

Actual result

1. The price and weight are not saved and are not returned in the result of the POST request.

I traced this down to the BeforeEntitySave observer, where the price seems to be stripped off the product when $entity->beforeSave() is called. I did not continue research after that.

Workaround is to execute the post request again. During the update of the product, the price seems the be saved correctly.

This happens when product type_id field is not defined. Created internal ticket MAGETWO-58101. Thanks for reporting.

Thanks for the heads up!
