E4091

The type has no field with the given name.

It is possible that you made a typo and use a wrong field name to access the field of a struct.

Erroneous example

///|
priv struct Point {
  x : Double
  y : Double
}

///|
test {
  let point = Point::{ x: 1.0, y: 2.0 }
  inspect(point.z) // Error: The type Point has no field z.
}

Suggestion

You can either add the missing field to the struct, or use an existing field to access the struct.

///|
priv struct Point {
  x : Double
  y : Double
}

///|
test {
  let point = Point::{ x: 1.0, y: 2.0 }
  inspect(point.x, content="1")
  inspect(point.y, content="2")
}
