There seems to be a typescript error showing up as
Error: Property 'type' does not exist on type 'never'export const getSomething = (actionLog: [] | undefined) => {
console.info(actionLog[length - 1].type)
}
Can anyone help identify and explain what is causing this issue?
A simple fix is to specify a type for the 'type' property:
export const retrieveInfo = (dataLog: {type: string}[] | undefined) => {
console.info(dataLog[length - 1].type)
}
UPDATED SOLUTION:
export const retrieveInfo = (dataLog: {type: string}[]) => {
if (dataLog && dataLog[0]) {
console.info(dataLog[length - 1].type)
}
}
