Having trouble getting Angular Material's mat-autocomplete to function properly when the application is in

I am currently in the process of incorporating a mat-autocomplete field, following the guidelines provided in the documentation. Everything functions as anticipated when tested on ng serve. However, after running ng build --prod and deploying to Firebase, the autocomplete feature does not work. No errors are displayed in the console. The field appears on the screen but fails to filter the data or trigger any events.

Upon checking my ng version, I found:

ng version

--I had to include an image link as inserting HTML directly was proving problematic even with correct indentation using ctrl + K.

The attached functions can be viewed here:

Although all elements function correctly locally - filtering, triggering events, selecting items, and processing data before sending to the backend API - they do not work once deployed.

Answer №1

After updating most of my angular dependencies and running npm install, the code started working. I had version 10.0.10 for angular modules and 10.1.3 for material. After the update, they were at 10.2.5 and material at 10.2.7.

I also experimented with using formControlName related to mat-autocomplete, but it seemed to break the component. In the end, [formControl] directive was the one that worked, even though it is not mentioned in the documentation.
