Do not continue checkout if no shipping rates available

Good idea! Thank you for working on this.

#3 fixes illegal choice error when I do not have a default shipping method and click recalculate shipping after entering an address.

Tested and it works fine.

One small nit, the doc comment needs to be formatted correctly to avoid a phpcs error, from

@inheritDoc

to

{@inheritdoc}

I've tested the patch in #3, which is working fine :)

I've also added a new patch with a simple modification as mentioned by @swickham in #5.

Jeeze, I really borked those metadata changes :)

Now with tests!

This patch works great. The interdiff removes a pesky 'createScreenshot' in the test.

The less graceful and uninformative error 'An illegal choice...' that previously came up has been replaced by more helpful: 'There are no shipping rates available for this address.'

👍

Thanks everyone, committing!

I'm using commerce_shipping 8.x-2.0-beta7 and have verified that this patch has been committed to it but for some reason it is not working.

In my tests I make a checkout order without any valid shipping methods. I do see the message in the shipping information pane that states:

"There are no shipping rates available for this address."

However, I am still allowed to complete my checkout without any further warnings and prevention.

I see in the patch that it looks like it should be preventing the checkout if no valid methods are found and display the following message:

"A valid shipping method must be selected in order to check out."

But this is not occuring. Any ideas why?

@3CWebDev Did you find a solution to this in the end? I am facing this issue with version 8.x-2.1.
