The currency in your feed does not match the country your data source is targeting. Error 169 is a warning - products still ingest, but they may be ineligible for distribution in that market.
The country your catalog is configured for expects its native currency (US > USD, UK > GBP, DE > EUR), but the price field is in a different currency. This happens often when a single feed serves multiple markets without country-specific overrides, or when a US-headquartered brand exports everything in USD even for UK feeds.
