I have built serverless architecture for wordpress (reference: https://keita.blog/2019/06/27/serverless-wordpress-on-aws-lambda/ ) and created custom runtime for wordpress (reference: https://github.com/stackery/php-lambda-layer ). So the problem is while trying to lauch wordpress in browser it shows as below

and after I entered the username and other details it was shows successfully installed but I can't able to move to wp-admin page as it shows redirection error like shown below

So, help me out to resolve these issues. Thanks in advance.
