The specified property is not found in type (2339)

I encountered a TypeScript error stating 

Property 'UPDATE_COLUMNS' does not exist on type 'DimensionAction'.ts(2339)
, even though it is clearly defined above.

This issue occurred while using VSCode. I'm starting to suspect it may be an IDE bug, as running yarn lint reveals that the syntax in all other parts of my code is correct.

https://i.sstatic.net/ooTSp.png

export enum DimensionAction {
    UPDATE_ROWS = 'update_rows',
    UPDATE_COLUMNS = 'update_columns',
}

const dimensionReducer = (state: Dimension, action: DimensionAction): void => {
    switch (action) {
        case action.UPDATE_COLUMNS:
            break
        case action.UPDATE_ROWS:
            break
        default:
            throw Error('Must pass action')
    }
}

What could be causing this TypeScript validation error?

Answer №1

Make sure to access the specific enumeration directly from the enum type.

case DimensionAction.UPDATE_COLUMNS:

It's not necessary to have a separate case for UPDATE_ROWS; it can be handled within the default case. The action: DimensionAction ensures that action cannot be null, undefined, or any value other than those specified in the DimensionAction enum.
