MS_MAX_CONCURRENT_REQ #127

Closed ghost closed 2 years ago

ghost commented 2 years ago

Hi,

sometimes I get

MS_MAX_CONCURRENT_REQ: Your Request for VAT validation has not been processed; the maximum number of concurrent requests for this Member State has been reached. Please re-submit your request later or contact TAXUD-VIESWEB@ec.europa.eu for further information"

and really do not now why. Could not find any proper information as well.

Is there any workaround for this one?

What's the full exception stack trace?

ghost commented 2 years ago

Actually there is no stack since it never throws exception. I am using

$vat_details = VatCalculator::getVATDetails($request->vat_number)

and the $vat_details were always false for a while. The I did dig it via a wsdl browser then the browser shows the error. Then 10 - 15 mins later it has started to return true. Not sure it is because of my local development or something else.

Cheers.

Found this: https://ec.europa.eu/taxation_customs/vies/help.html

I'm afraid this isn't something we can solve within the library. The VIES API has a reputation of being unreliable at times. I have no idea how to even start preventing this.
