I am programming in angular and create an api server in express, I have a little problem when I have been programming and making requests in the API for hours. What happens is what arrives as a maximum number of requests and throws me an error.
The operation is fine nothing fails me, it is only after a while that I get that error and for that reason the database is disconnected and my frontend in angular works.
After a while the server throws this error at me

Someone, who can help me with this problem, only appears when I have been programming for a while.
max_connect_errors defaults to 100. When you are using connection pools this means a number of sparatic errors can quickly add up to 64 resulting in the error experiences.
Solution part 1: remove the connection pooling. Simple per connection is ok.
Solution part 2: increase max_connect_errors to its documented maximium
Solution part 3: try to identify some of the errors that occur and see if they are programmatic mistakes or transient network connection problems.
Sometimes when I download multiple files from S3 bucket using node sdk, the request will timeout for one of the downloads. I would like for the request to just retry to attempt to download again.
The json error response says retryable: false.
Is there a way I can configure it to be true?
Here is the error:

I am not sure of how you are using the resources as you didn't share your code, but this might help you.

So i keep getting this error which redirects me to node_modules and I'm not sure if I would check there.. Everything was fine until node.js version update yesterday.
