Subscription Upgrade Issue- Error: "Something went wrong on our end. Please try again."

[Nikhil-MathBud]

Hi everyone,

I am trying to implement an upgrade subscription plan in my app using CHARGE_PRORATED_PRICE. However, when I attempt to upgrade, the Google payment modal does not open. Instead, I get the following error message:

Error:- "Something went wrong on our end. Please try again."
When logging the error in the catch block, I see:- "Google is indicating that we have some issue connecting to payment."

Interestingly, if I use replacementModeAndroid: 3 //(WITHOUT_PRORATION), it works fine and deducts the full amount instead of a prorated price.

try {
await requestSubscription({
sku: productId,
purchaseTokenAndroid: oldPurchaseToken,
replacementModeAndroid:2, //CHARGE_PRORATED_PRICE
...(offerToken && {
subscriptionOffers: [{
sku: productId,
offerToken}],
}),
});
} catch (error) {
console.error("Error while requesting subscription:", error);
}

• My app is in Internal Testing on Google Play Console.
• I am logged in as a Test User on Google Play Console and using the same account for test payments.
