Elastic Beanstalk app suddenly stopped working

I deployed this app on AWS Elastic Beanstalk and it was functioning correctly over the last week.

I am now getting these three errors in the logs every time I run the app.

When I run the app locally, it works fine…

The app currently loads fine and appears to execute fine, but at one particular step, the user clicks a button which generates a datatable, and this datatable just never appears on the screen…

Any help is greatly appreciated!

Sorry, I am not able to answer your question. I am new to the forum and am having a very hard time deploying an app to Elastic Beanstalk. Is there a tutorial you found most helpful? (I’ve tried so many that I am confusing myself more…)
