Error: [UNPROCESSABLE_ENTITY] TAX_TOTAL_MISMATCH

[UNPROCESSABLE_ENTITY] The requested action could not be performed, semantically incorrect, or failed business validation. https://developer.paypal.com/docs/api/orders/v2/#error-TAX_TOTAL_MISMATCH

We are consistently seeing this error during checkout under the following scenario: customer applies a COUPON CODE, is from the state of Minnesota (the only state that we charge sales tax), and clicks the Paypal button.

We turned on logging and found that the tax amount that is being sent to Paypal is calculated based on the non-discounted amount (before the coupon code). It should be calculating 6.875% tax based on the discounted amount. The tax that is shown on the checkout page is correct, but it’s what is getting passed through the API that is incorrect.

Here is a snippet from the log. Discounted price in cart is $75, so the tax amount should be $5.16, but it shows as $6.54 below.
