minDeliveryDate in Shopify Flow doesn't work anymore

I have created a flow that adds the estimated latest delivery date to the notes field of an order. Since last week Wednesday/Thursday this no longer works.
The flow runs without any problems, but minDeliveryDateTime is no longer output and therefore no longer printed in the notes field.

Does anyone know why this could be? Nowhere in the changelog could I find that anything has been changed to minDeliveryDate.

I can still add fulfillment.minDeliveryDateTime as a variable in a flow, but nothing is output anymore.

I am grateful for any help.

I’m not familiar with that field and it’s not in the API: Fulfillment - GraphQL Admin

I don’t see any reference to it in the docs. It’s possible that was an undocumented change and was removed.

There is this field on fulfillmentOrders: FulfillmentOrders.deliveryMethod. minDeliveryDateTime

FYI, some changes are coming to returns. Details here Migrate to return processing

Thank you for the quick response. Now it works again, although nothing has been changed in the code. :laughing:

Assuming that you are using the variable I put above, both deliveryMethod and minDeliveryDateTime can be null. So I’d expect it to be empty sometimes.

I use the variable you mentioned. If the customer is shown an estimated delivery date in the checkout, then it is very very unlikely that the variable minDeliveryDate is null, isn’t it?

Depends on what you are using in checkout for that and what the customer does. Checkout data is not necessarily passed to Order data.

Might help to share an end-to-end video here if you think there might be a bug
