Magento2 Wrong base url on ajax call

[mandar_parbate1]

Hi,

I have upgraded the Magento version to 2.3.4. After that, I had a strange issue on the checkout that when we trying to call ajax function the URL is been wrongly generated. Previously it was like

<website>/rest/default/V1/guest-carts/AC72N37Vmo3uGMIXEVQfIDt1ubuZLJws/estimate-shipping-methods

but  after upgrading Magento version now it's 

<website>/checkout/undefinedrest/default/V1/guest-carts/AC72N37Vmo3uGMIXEVQfIDt1ubuZLJws/estimate-shipping-methods

it comes with the current URL which throughs I error while proceeding further.

Can anyone help me out from this?

Thanks in Advance.

Hello @mandar_parbate1 

Can you please check base url secure and non secure url ?

if it is empty then enter your base site URL

Hi @Sunil Patel ,

I checked the secure & unsecured URL's. Both are fine.

In my controller I want to receive the data that I sent with this post request and make a CSV file outta it. But it seems that my controller Sarkari Result  Pnr Status  192.168.1.1  doesn't get the post request ?
