I am using
createEmptyCart mutation for create customer Quote Id or Mast Id.
createEmptyCart mutation write in
vendor/magento/module-quote-graph-ql/etc/schema.graphqls file and use resolver file
Magento\QuoteGraphQl\Model\Resolver\CreateEmptyCart. But in this Resolver file
$customerId = $context->getUserId(); getting blank customer id, I have not idea how to set user id or customer id in
ContextInterface, We need to set in GraphQA query or API header.
Please let me know if anyone have idea.
