Problems migrating from Odoo14 to Odoo17 due to web.assets_backend problem

Question

Hey, I'm migrating my Odoo service EE Odoo 14 to Odoo 17. I'm testing the 17 community version. However, I cannot install personalized modules due to the following error:
ValueError: External ID not found in the system: web.assets_backend
I have followed previous forum suggestions, also made on SO. However, I cannot get it to work. Seems to me that a paid module is necessary particularly the web_studio one from the Odoo17 store.

Is this true or any ideas on how to solve the issue? I have change

Hello David Saint,

Hope you are doing well.

- Please add below code in your manifest file.

'assets': {
'web.assets_backend': [
'your_module_name/static/src/**/*',
'your_module_name/static/src/views/**/*',
],
},

- So, we will add this code in your manifest file and try it
I Hope this information proves helpful to you.
