Latest merge broke the Invoices (0165a64)

[lucacri]

Hello,
after the latest merge,
$invoices = \Stripe_Invoice::all(["count" => 100]);

will return the error

[ErrorException] array_keys() expects parameter 1 to be array, null given
in stripe-php/lib/Stripe/Object.php:138

Only way to have it working, at the moment, is to revert to a previous version.

I have the same problem here!

I'm having the same problem as well.

Same problem. I reported this to customer support, and ti has been escalated internally. For the time being, I downgraded to version 1.8.3 which resolved the problem.

Same issue here.

I think that this might be due to the "metadata": null in some events. I have some json that doesn't not have this field and I do not receive this error.

Thanks for reporting--this was indeed due to metadata being added to invoice items. Subscription line items in invoices don't have metadata and thus return null rather than {} as its metadata. These warnings should no longer show up in the latest version.

Sorry for any inconvenience!
