Explanation: You can only access fields on records, like this:
┌─────────────────────────────────┐
│ { foo = True, bar = "ABC" }.foo │ This is valid ...
└─────────────────────────────────┘
┌───────────────────────────────────────────┐
│ λ(r : { foo : Bool, bar : Text }) → r.foo │ ... and so is this
└───────────────────────────────────────────┘
... but you cannot access fields on non-record expressions
For example, the following expression is $_NOT valid:
┌───────┐
│ 1.foo │
└───────┘
⇧
Invalid: Not a record
You tried to access a field named:
↳ $txt0
... on the following expression which is not a record:
↳ $txt1
... but is actually an expression of type:
↳ $txt2
Some common reasons why you might get this error:
● You accidentally try to access a field of a union instead of a record, like
this:
┌─────────────────┐
│ < foo : a >.foo │
└─────────────────┘
⇧
This is a union, not a record
