GET /V1/carts/mine/items is returning "cartId is a required field"

[sauberia]

The webapi.xml for Quote specifies the getList method but I believe this should be getListForCustomer instead.

    <route url="/V1/carts/mine/items" method="GET">
        <service class="Magento\Quote\Api\CartItemRepositoryInterface" method="getList"/>
        <resources>
            <resource ref="self" />
        </resources>
        <data>
            <parameter name="customerId" force="true">%customer_id%</parameter>
        </data>
    </route>

Likewise, PUT /V1/carts/mine/items/:itemId should use saveForCustomer and DELETE /V1/carts/mine/items/:itemId should use deleteByIdForCustomer.

Here is a ruby hash of the the request and response:

I just encountered this issue in Magento 2.1.5 when checking out as a registered user with a saved address. It is preventing the user from selecting a shipping method. I have traced the error to a 400 Bad Request...

Request URL = .../rest/us/V1/carts/mine/estimate-shipping-methods-by-address-id
Request Payload = {addressId: "60"}
Response:

I also encounter this issue eventually on Magento 2.1.3

[sydekumf]

I have the same error and debugged it. In the end there is something else wrong which I described here: #9744
It is because Magento hides the exception...

[MikeSheward]

I'm also getting this error, probably from #9744, any ideas how to resolve this?
