Ref url - Shipping address custom attribute value not getting in RateRequest object in Carrier Model in magento2.x

enter image description here Above link in working perfect in magento2.2.x but not in magento2.3.1. I checked magento2.3.1 in they have changed something with custom_attribute code.

the issue is reproduce Step below 1. Add to cart product after going checkout Mobile Type select - Local Estimation shipping rate is - 5 USD and address array passed like

estimate-shipping-methods - 
    address:{
    city: "GA"
    country_id: "US"
    custom_attributes: [0: {attribute_code: "mob_type", value: "Local"}]
    firstname: "Test"
    lastname: "Dev"
    postcode: "30049"

.....
  1. Once back to checkout cart page change postcode I am getting an error -

Error occurred during "custom_attributes" processing. A custom attribute is specified with a missing attribute code. Verify the code and try again.

I checked post address in estimate-shipping-methods api and found data like

estimate-shipping-methods - 
        address:{
        city: "GA"
        country_id: "US"
        custom_attributes: [0: {attribute_code: "0", value: {attribute_code: "mob_type", value: "Local"}}]
        firstname: "Test"
        lastname: "Dev"
        postcode: "30049"

    .....

both custom_attributes arrays is different - so i checked core code and found custom_attributes: [0: {attribute_code: "0", value: {attribute_code: "mob_type", value: "Local"}}] is worng. attribute_code: "0" is extra adding so How can i fix this issue anyone have idea?

This appears to be a core bug to which I've opened an issue on github https://github.com/magento/magento2/issues/27505.
