templating | tools needed to build any kind of template system

I'm stuck to get data from gathered fact, using calculated data as part of query.

I am using 2.9 ansible and here is my task

I have the following JSON file.

I'm trying to upload images to my server using Multer. If I use any templating engine, the req.file and req.files are working fine. But when I try to upload images with postman or jsx form in react, It returns undefined.

I'm using: Multer - 1.4.2 Express - 4.17.1 Node - 14.16.1

server.js

I am new to Django and API creation. I am trying to figure out if it is better to use djangorestframework or just use JsonResponse. I got the suggestion of djangorestframework from Digital Ocean's tutorial but also found out about JsonResponse, which seems simpler given that I don't have to install another package.

Goal: I would like to be able to provide user information for both web and mobile applications.

I see that there are some reasons provided on this post for djangorestframework, which I pasted below for posteriority.

The common cases for using DRF are:

1)You're creating a public-facing external API for third-party developers to access the data in your site, and you want to output JSON they can use in their apps rather than HTML.

2)You're doing mobile development and you want your mobile app to make GET/PUT/POST requests to a Django backend, and then have your backend output data (usually as JSON) to the mobile app. Since you don't want to pass back HTML to the mobile app, you use DRF to effectively create a REST API that your mobile app can call.

3)You're creating a web app, but you don't want to use the Django templating language. Instead you want to use the Django ORM but output everything as JSON and have your frontend created by a JavaScript MVC framework such as React, Backbone, AngularJS, etc. In those cases, you can use DRF to output JSON that the JavaScript framework can process.

I have a Flask web application which I tested locally on my PC. Locally, everything is working correctly - no issues. So, I have moved on and deployed my Flask application on a Ubuntu 20.04 server behind uWSGI and Nginx. The issue I am facing now is, that my custom filter for Jinja2 template is 'Undefined'. I am not sure where the issue is, at all.

The error I get is:

I'm working on something similar to a text templating engine.
I'm providing metadata from my server to the client to represent an javascript version of the access path for instance:

Say I have a DTO:

I am trying to use the request.pathSegments to render some information in a response and that placeholder is empty...

using 2.26

Wiremock standalone start up cmd:

java -jar ./wiremock.jar --root-dir "/usr/share/wiremock" --verbose --local-response-templating

Stub definition:

So I'm using this ansible playbook:

I'm currently struggling to have a working playbook using regex_search, I'm trying to have the playbook go through the stdout of a network command (show run vlan ID) and then go through a regex expression which will extract all the interface tagged,

ultimately that variable would be use to deploy a new vlan and match the configuration of the existing working vlan

here is the code I'm trying however that return the following error;

fatal: [10.163.199.131]: FAILED! => {"msg": "Unexpected templating type error occurred on ({{ results.stdout.lines | regex_search(regexp,'\\1') }}): expected string or buffer"}

here is the output of the STDOUT
