Issue with Swagger UI Endpoint Access via FQDN vs. IP Address

Discussed in https://github.com/orgs/vivifyhealthcare/discussions/54

^{Originally posted by sacredabhishek February 20, 2024}
When utilizing Swagger UI for the API with a Fully Qualified Domain Name (FQDN), an error occurs for the endpoint. However, the same endpoints function correctly when accessed via IP. What could be the potential reason for this issue?

The backend technology stack consists of Python and Django.

The error message received is:

Failed to fetch.
Possible Reasons:
- CORS (Cross-Origin Resource Sharing) issue
- Network Failure
- URL scheme must be "http" or "https" for CORS request.

I'm exploring the use of Python-dotenv for managing environment variables and secrets in my Python projects.
While it seems straightforward to implement, I want to ensure that I'm following best practices for keeping sensitive information secure.
Could someone please provide a detailed explanation or guide on how to effectively utilize Python-dotenv to manage secrets safely?

• Any tips,
• recommendations, or
• examples

on securely handling sensitive data within a Python environment would be greatly appreciated. Thank you!

Resolving Angular Application Memory Allocation Error

Discussed in https://github.com/orgs/vivifyhealthcare/discussions/60

^{Originally posted by sacredabhishek February 20, 2024}
Recently encountered a frustrating error while trying to run my Angular application. The error message I'm receiving is as follows

<--- JS stacktrace --->

FATAL ERROR: Ineffective mark-compacts near heap limit Allocation failed - JavaScript heap out of memory
----- Native stack trace -----

Here's some additional context:

• command to execute Angular Application

ng serve --port=4200 --host=0.0.0.0

• full error log

Warning: This is a simple server for use in testing or debugging Angular applications
locally. It hasn't been reviewed for security issues.

Binding this server to an open connection can result in compromising your application or
computer. Using a different host than the one passed to the "--host" flag might result in
websocket connection issues. You might need to use "--disable-host-check" if that's the
case.

This error seems to be related to memory allocation issues, but I'm unsure how to address it.
Has anyone else encountered a similar problem while running Angular applications?
Any insights or suggestions on how to troubleshoot and resolve this issue would be greatly appreciated.
