"Please specify a shipping method" Exception

[vphat28]

Steps to reproduce

1. Install Magento from develop branch.
2. Install 3rd test shipping provider
3. Able to show rate in checkout page
4. Able to choose payment methods
5. Click on "Place order"
6. Exception is throwed "Please specify a shipping method"

Expected result

1. Should go to success page

Actual result

1. Exception is throwed "Please specify a shipping method"

I searched for the string and in file \vendor\magento\module-quote\Model\QuoteValidator.php line 53
the $method variable is null

My collectrates in shipping adapter is
$method = $this->_rateMethodFactory->create();

        $method->setCarrier($this->_code);
        $method->setCarrierTitle($this->getConfigData('name'));

        $method->setMethod('express_method');
        $method->setMethodTitle($this->getConfigData('express_title'));

        $method->setPrice($this->getConfigData('express_price'));
        $method->setCost($this->getConfigData('express_price'));

        $result->append($method);

I noticed that when I remove the underscore symple and change $method->setMethod('express_method'); to $method->setMethod('expressmethod');
the checkout went through successfully.

I wonder can I use "_" symbol in function setmethod? I don't have this problem in magento 1

I need to modify my code to this , and checkout went through

        $code = str_ireplace('_','',strtolower($code) );
        $method = $this->_rateMethodFactory->create();
$method->setMethod($code);

I have remove underscore too, but no success.

The error message ("Please specify a shipping method") still showing

@lutpiero you may need to covert string to lower also

[lutpiero]

Same as yours, but still no luck

Hi @vphat28! Please specify what 3rd party shipping provider do you use?

I have also been experiencing this with our Meanbee Royal Mail extension for Magento 2.

After adding a log line to \vendor\magento\module-quote\Model\QuoteValidator.php. I also can see that a method code is fetched but no rate.

The logging suggests that the method code has been truncated and so when it tries to find a rate it is unable.

Royal Mail Method: meanbee_royalmail_firstclasssignedforsma {"is_exception":false} []

The code above should be "meanbee_royalmail_firstclasssignedforsmall".

When I change the Carrier code to "rm" and therefore the shipping code reduces to "rm_firstclasssignedforsmall" without being truncated, the PayPal Express order with review step enabled works.
