How to update product prices in existing markets?

Hi all,

We’ve been trying to update the prices of our products in our different markets without much success. We followed the steps here https://shopify.dev/docs/apps/markets/catalogs/getting-started but we found they would only work for newly created markets.

For our existing markets where we had already set some fixed prices on the admin we would always get an error when trying to associate a new price list with the market’s catalog, using priceListUpdate. We also tried the catalogUpdate mutation to do this, but we would get the same error.

What is the proper way of doing this if you have markets with fixed prices that have been set in the admin?

Thank you
