How to print / echo / debug RateRequest properties in custom shipping method

Question

I'm able to use this city dropdown plugin successfully.

Now I'm trying to call shipping vendor API in my custom shipping module.

Can anyone help me how I can print / echo / debug the destination in Vendor\Module\Model\Carrier\CustomCarrier -> collectRates(RateRequest $request) method / any JS class when user select their region / city ?

I've tried showing the RateRequest properties following this answer with :

• echo $request->getDestRegionCode(); or $request->getDestCity();
• debugging to browser console
• Logging the variable to debug.log / system
• $this->debugData($request->getDestRegionCode());

but still not visible , and the application mode has been set to developer as well previously.

Any help is appreciated. Thank you in advance.

Edit : I'm trying to get the destination value when the user select region / city. So the shipping price will change dynamically.

You can create custom log file to debugging. this is a alternative method.

$writer = new \Zend_Log_Writer_Stream(BP . '/var/log/my_debug.log');
$logger = new \Zend_Log();
$logger->addWriter($writer);
$logger->info('This Is Simple Text Log'); //To print simple text log
$logger->info(print_r($myarray, true)); //To print array log

Write data into custom log file and check it via manual or CLI like

tail -f var/log/my_debug.log

After debugging, delete the custom log file.
