Odoo module upgrades, done for you
Error: "attrs" is not a valid attribute on field — Odoo 17
The exact error — usually in this shape — means your views still use the pre-17 syntax:
odoo.tools.convert.ParseError: while parsing my_module/views/order_views.xml:24
Since 17.0, the "attrs" and "states" attributes are no longer used.
View: order.form.inherit in my_module/views/order_views.xmlEvery occurrence in every XML file has to be rewritten to the new inline-expression syntax (invisible=, readonly=, required=, column_invisible=). See the full before/after on our attrs/states fix page.
Send us the module. This is the most common Odoo 17 upgrade failure and we fix it routinely. Try the ported module live, then $50 to download.

Common questions
Can I just delete the attrs attribute to make the error go away?
The view will load, but every conditional visibility/required rule silently disappears — fields show when they shouldn't. Each attrs domain needs translating to an equivalent Python expression.
