A possible and promising approach is to generate the Pydantic model starting from the corresponding JSON Schema of the STIX object.

Luckily enough the JSON schemas for all the STIX 2 objects have been defined by the OASIS Open organization on the GitHub repository CTI-STIX2-JSON-Schemas.

In particular, the JSON Schema for the Attack-Pattern is available here.

Before setting up a brand new TURN server you can try to understand what's actually happening: if you take a trace on the computer with an application like Wireshark, and filter for stun messages, you should be able to see the browser sending Binding Request and Allocate Request methods towards the TURN server.

A missing response from the server may mean that the server is not available, the port is wrong, or a firewall prevents the browser to reach the TURN server.

If instead the credentials are wrong, the browser will receive a 401 error to the Allocate Request with the message-integrity attribute.

You can also verify the TURN URL and credentials by running the WebRTC sample application that deals with ICE candidate gathering at https://webrtc.github.io/samples/src/content/peerconnection/trickle-ice/ .

you can use combineLatest:

combineLatest is an operator which you want to use when value depends on the mix of some others Observables. When an item is emitted by either of two Observables, combine the latest item emitted by each Observable via a specified closure and emit items based on the results of this closure.

First, let's clear up a misconception. The view model is not where you "make action." The view model is where you want logic. There should not be any relays, subjects or observers in your view model. It should be Observables in, Observables out.

Second, when defining an Observable chain, much like when you are defining a formula in a cell of an Excel spreadsheet, the final result, the thing you want to ultimately do, is the most important part but that is the one thing you haven't described. I doubt that all you want to do is print something.

Third, a Subscription, just like a use-case, consists of a Cause and Effect, with Logic transforming the cause into an effect. The Logic is what goes in the view model, an here the only logic you have described is that "tap" should be the output every time the button is tapped.

So as it stands, the entire use-case you have described is "when the user taps the button, the system should print 'tap'." With only that to go on, we have a Cause (the button tap), the Logic (the word "tap" once per tap) and the Effect (print something.) Which would be modeled like this:

The issue is coming from your targeted element being transitioned in off screen. When you click on the anchor, the #panel element is in focus/selected, and the browser will attempt to move the viewport in a way such that the element remains visible in the viewport. Since your element is rendered outside the viewport but slides in after, this causes the browser to keep adjusting its horizontal scroll position to keep it in view.

A possible workaround is to simply wrap the contents of #panel in an inner

depending on security requirements. Assuming that the Desktop PC and raspberry pi are on the same network, you could create an HTTP REST endpoint on the pi, you could use flask or fastapi for this. then call that from the app running on the desktop. for help with flask see https://flask.palletsprojects.com/en/2.0.x/ if you are familiar with python flask is fairly simple to get started with.

I was able to finally resolve this after much troubleshooting. Here's what worked.

1. I kept the original setup the same: Sendgrid for SMTP using their python lib (no Postfix or smtplib), using user crontab (using $ crontab -e not $ sudo crontab -e), and using Python 3.7.
2. Apparently the word 'email' in the python script name can cause interpreter issues so I renamed the file to remove the word 'email'. For example, send_noti.py instead of send_email.py
3. I used absolute paths for every call to a file in the python script. I was reading, writing, and executing files in the user directory in my python script as well as sending an email. Those R,W,X commands started erroring out in cron but not when called from outside of cron for some reason, even after renaming the file. Using absolute paths for all references to files fixed that.
4. I also used the absolute path for the python file in the crontab file. For example, * * * * * python3 /home/ec2-user/apps/send_noti.py instead of * * * * * python3 ~/apps/send_noti.py
5. I removed the unnecessary items in the crontab file I had put in before such as redefining the PATH directory.

I hope this helps someone because this took me about 3 weeks to troubleshoot and figure out.

As commented, Jackson doesn't find "ID" field so it throws an exception. You can add @JsonProperty("ID") on top of id field in ItemDto:

There is now not-in - similar to in which matches a single field to any entry in an array, but in this case NOT in the array.

https://firebase.google.com/docs/firestore/query-data/queries#in_not-in_and_array-contains-any

Limited to an array of 10 entries or less, which fits your use-case of two values.

Also Note: any field used in a query will automatically reject all documents that do not have that field.
