Stripe how to handle InvalidRequest error - php

Question

I want to handle this error, however I can't get it to work in my catch. I've tried using multiple error phrases such as Stripe\Error\InvalidRequest and invalid_request_error, but none of them work.
Note: I have only included the necessary code, my payment system works fine.
Here's my code:
try {
$charge = \Stripe\Charge::create(array(
'customer' => $customer->id,
'amount' => $amount,
'currency' => strtolower($active_user->currency->currency_id)
));
}
catch (Stripe\Error\InvalidRequest $e) {
$msg = "Sorry, you cannot make the same payment twice.";
}

Answer 1

From the Stripe API Docs section on errors:
catch (\Stripe\Error\InvalidRequest $e) {
// Invalid parameters were supplied to Stripe's API
} catch (\Stripe\Error\Authentication $e) {
// Authentication with Stripe's API failed
// (maybe you changed API keys recently)
} catch (\Stripe\Error\ApiConnection $e) {
// Network communication with Stripe failed
} catch (\Stripe\Error\Base $e) {
// Display a very generic error to the user, and maybe send
// yourself an email
} catch (Exception $e) {
// Something else happened, completely unrelated to Stripe
}

Could be a namespacing issue. Try referencing your exception class with respect to the global scope by using a leading slash:
catch (\Stripe\Error\InvalidRequest $e) {
Failing that, add a catch for the base PHP Exception class, and see what you can find out about what is being thrown.

Example from stripe:
Are your responses set to return json, If so, in your } catch (... $e) {
$body = $e->getJsonBody();
$err = $body['error'];
print('Status is:' . $e->getHttpStatus() . "\n");
print('Type is:' . $err['type'] . "\n");
print('Code is:' . $err['code'] . "\n");
// param is '' in this case
print('Param is:' . $err['param'] . "\n");
print('Message is:' . $err['message'] . "\n");
