I am doing an app that generates preapprovals (basic subscriptions) in MercadoPago with nodeJS (loopback, specifically).
The problem is that I can not pay in any way in sandbox mode with the sandbox url that gives me mercadopago: When I enter the url that appears to me:
gives me to choose the credit card of the test that offers paid market
But choose the card you choose (the one that ends in 1111 and 2222 should be accepted, according to mp ), they all give me or this error (for the record that I chose the one that ends in 1111, not the one in 7777 that should give an error):
or I get a message saying "there was an error, and try later"
The only feedback I have while creating the subscription is that when I create it, it says "payer_email" is not a valid property (as a warning, because it lets me create the same preapproval) but by eliminating the property tells me that it is required, and when inventing an email that does not exist, it throws me another error. My marketpay api is set
mercadopago.configure({ client_id: config.client_id, client_secret: config.client_secret });
and I tried doing this by setting flag sandbox: true and I had the same results. I do not know what I'm doing wrong, and I do not see any other market error showing that it may be happening ...
I have already managed to generate the subscriptions, and to return the subscription object, and I have even configured everything for the notifications of mercadopago. But I can not keep proving if I'm stuck here ..
