Hi there

Can you provide a request ID for this error?

[frozen epoch]

yeah let me look

{"errors":[{"title":"Internal Error","detail":"Currency and interval fields must match across all plans on this subscription. Found mismatch in interval field."}],"stack":["Error: Currency and interval fields must match across all plans on this subscription. Found mismatch in interval field."," at Function.generate (/var/task/node_modules/stripe/lib/Error.js:40:16)"," at res.toJSON.then.StripeAPIError.message (/var/task/node_modules/stripe/lib/StripeResource.js:220:35)"," at processTicksAndRejections (node:internal/process/task_queues:96:5)"]}

Do you see a failed request in your Dashboard at: https://dashboard.stripe.com/logs ?

[frozen epoch]

i dont

oh nvm

req_44gBKdcj80pVPH

{
"error": {
"message": "Currency and interval fields must match across all plans on this subscription. Found mismatch in interval field.",
"request_log_url": "https://dashboard.stripe.com/test/logs/req_44gBKdcj80pVPH?t=1676656983",
"type": "invalid_request_error"
}
}

Thanks looking

Ah okay

So what you are actually doing here is adding on a Price

You need to pass the Subscription item ID as well to replace it

See: https://stripe.com/docs/billing/subscriptions/upgrade-downgrade#changing

So that's why you see interval mismatch right now

You are trying to preview having a monthly and yearly price

[frozen epoch]

but i am passing the subscription id

see:

the original price lives in [0] so we are just replacing that with the new price point

[acoustic pulsar]

Yeah this is a common confusion of how updating Prices works with Subscriptions

You have to provide the Subscription item ID

Not just the Subscription ID

See: https://stripe.com/docs/api/invoices/upcoming#upcoming_invoice-subscription_items-id

So for that Sub you are trying to preview, the Subscription Item is si_NNIlboolPAiKun

[frozen epoch]

okay so... it should look more like this:

{
"subscription": "sub_1MUVJtFNVbYFceRMG4m8GS4l",
"subscription_proration_behavior": "always_invoice",
"coupon": "100OFFLTD",
"subscription_items": {
"0": {
"price": "price_1IEJiNFNVbYFceRMExVoQTiJ",
"id": "sub_1MUVJtFNVbYFceRMG4m8GS4l"
}
}
}

is that right?

[acoustic pulsar]

Close

You don't pass the Subscription ID to subscription_items

You pass the Subscription Item ID

See: https://stripe.com/docs/api/subscriptions/object#subscription_object-items

When you retrieve your Subscription it will have a list of Subscription Items

So it would be like ```subscription_items": {
"0": {
"price": "price_1IEJiNFNVbYFceRMExVoQTiJ",
"id": "sub.items.data[0].id"
}
}

If you initialized your Subscription as a sub variable that is

[frozen epoch]

got it i think that makes sense

i wonder what the linking was around that

seems a bit complex

[acoustic pulsar]

Yeah it is a bit nuanced for sure

[frozen epoch]

i appreciate the guidance
