Checkout 'hanging' for 2 out of 3 websites running the SAME Magento code

[martijnhovinga]

I installed Magento 2 with Softaculous successfully. I only added code to .local host in Magento root for running 3 stores based on the same Magento installation (taking the added code out did not make any difference to the issue below).

On 2 of my stores, after adding to cart and clicking "Go to Checkout' the screen only displays the 'logo and the 'order summary' without the 'shipping' step, see https://babyplus.com.my/checkout Same for https://contoursbaby.com.my/checkout

On the third store however it consistently works fine, running the SAME Magento installation: https://babyfair.com.my/checkout

'Checkout with PayPal' works fine on all websites.

I compared the settings in Store/Config and cannot find any significant differences. Even after a new installation, the problem persists.

I had a well-known Magento extension developer have a look at this, however they could not find the solution. According to their professional opinion, this could be a 'bug'.

@martijnhovinga Thank you for reporting the issue.
Currently we can not reproduce described issue with clean magento installation.
Please try to install Magento in one of the recommended ways and test the same case without third-party modules to see if the issue persists.

@ishakhsuvarov Thanks for your feedback.
My assumption is that is a bug indeed in the STATE OPTIONS settings under default configuration. Initially I ticked Malaysia in 'State is Required for'.
This is similar to #1508

I found this Javascript error on the checkout pages of babyplus.com.my and contoursbaby.com.my:

/pub/static/frontend/Magento/luma/en_US/Magento_Ui/js/form/element/region.js:34
Uncaught TypeError: Cannot read property 'is_region_required' of undefined
does NOT occur on babyfair.com.my

After changing State Options Settings, the problem still persists in the 2 sites.

Solved for me - fix was to enable the country specified in the "Default Tax Destination -> Default Country" in "Country Options -> Allowed Countries"

Thank you very much! This worked for me as well! PROBLEM SOLVED!

@daim2k5 -- Why'd the ticket get closed? It's great these users solved their problem, but it sounds like they had a valid configuration of Magento that ended up creating javascript errors that blocked other page functionality, and was hard to diagnose. Shouldn't the platform fix that?

[srynot4sale]

Agreed - this is a horrible bug. Needs to be prevented from occuring

@martijnhovinga Since you seem to have figured out a way to resolve your issue, would you be able to try providing steps to re-create the issue for the Magento team to be able to reproduce and solve the underlying bug? This definitely sounds like a bug; an obscure misconfiguration such as this should not be able to cause JS errors on the front-end like this.

If I read you right, steps may be something like a) setup store; b) set "State is Required for" to something; c) bug (with workaround being to also configure other setting.

@davidalger Without doubt, this is a bug. Even worse, it affects the most vital part of the system, i.e. the checkout process and most customers who wish to buy and face this problem get frustrated and decide to leave the website.So I am very thankful that you will look into this for the sake of others using the system.
The problem was caused by a discrepancy between Default Country and Default Tax Destination Calculation.

The settings in default configuration when the problem occurs are as follows:
"Stores > General > Default Country: Malaysia and >Allowed Countries: Malaysia & Singapore"
and
"Stores > Sales > Tax > Default Tax Destination Calculation: United States"
This resulted in a Javascript error:
/pub/static/frontend/Magento/luma/en_US/Magento_Ui/js/form/element/region.js:34
Uncaught TypeError: Cannot read property 'is_region_required' of undefined

By changing only
"Default Tax Destination Calculation to my default Country, i.e. Malaysia, the problem was solved.

I also configured 2 additional websites, however I don't believe that is relevant. The only surprise was that it worked like a charm in one of the 2 additional stores.

If you want to have access to my production system to check and reproduce, I am willing to grant that depending on the timing (I am in Malaysia/Singapore time zone).

My recommendation is that the value of Default Tax Destination Calculation would be synchronized automatically with the value of the Default Country.

Thank you all.
