What is expected?

I want to get the value from data

What is actually happening?

I get an error when trying to get value

It happens when I have a base component with data and provide. I extend another component with the base component.

As a workaround, you can use this.$data.a inside of updated

accessCache is incorrect when next code run. provide() { return { a: this.a } } It should be 1(AccessTypes.DATA)
