Can't resolve 'fs' but in an API route???

Any idea why this error is occuring? I thought all api routes are node compatible...

Type interface of map error

interface TableData {
    [databaseName: string]: number;
}
function foo(): TableData {
    let tableData = new Map<TableData>();
    // No overload expects 1 type arguments, but overloads do exist that expect either 0 or 2 type arguments.

    tableData.set('database1', 123);
    return tableData
}

interface TableData {
    [databaseName: string]: number;
}
function foo(): TableData {
    let tableData = new Map<TableData>();
    // No overload expects 1 type arguments, but overloads do exist that expect either 0 or 2 type arguments.

    tableData.set('database1', 123);
    return tableData
}

Why does this not work? I have been googling for over 40 minutes but I don't get it. I know I could do something like new Map<string, number>() but why not by using the interface? Thanks!
