Error fetching offerings although products are returned from Play Store

I am getting product details from Google play store, but purchase action fails on "None of the products registered in the RevenueCat dashboard could be fetched from the Play Store”
Product returned:

{"productId":"getbill_299_1m_1m0","type":"subs","title":"Monthly subscription 1m free (App name)","name":"Monthly subscription 1m free","localizedIn":["en-GB"],"skuDetailsToken":"<token>","subscriptionOfferDetails":[{"offerIdToken":"<token>","basePlanId":"basic-1month","offerId":"free-1m","pricingPhases":[{"priceAmountMicros":0,"priceCurrencyCode":"EUR","formattedPrice":"Free","billingPeriod":"P1M","recurrenceMode":2,"billingCycleCount":1},{"priceAmountMicros":3590000,"priceCurrencyCode":"EUR","formattedPrice":"€3.59","billingPeriod":"P1M","recurrenceMode":1}],"offerTags":["basic-1month"]},{"offerIdToken":"<token>","basePlanId":"basic-1month","pricingPhases":[{"priceAmountMicros":3590000,"priceCurrencyCode":"EUR","formattedPrice":"€3.59","billingPeriod":"P1M","recurrenceMode":1}],"offerTags":["basic-1month"]}]}

On purchase action:

E/[Purchases] - ERROR( 5179): 😿‼️ Error fetching offerings - PurchasesError(code=ConfigurationError, underlyingErrorMessage=There's a problem with your configuration. None of the products registered in the RevenueCat dashboard could be fetched from the Play Store.
