Typescript: Type 'string' is not assignable to type 'FieldType'. influx@next

[shadow1349]

I am trying to use influx with my typescript/express app, but I cannot assign any strings in fields. here is my example:

import * as influx from 'influx';
import { Request, Response, NextFunction } from 'express';
import * as os from 'os';

const Influx = new influx.InfluxDB({
  host: 'host',
  database: 'my_database',
  schema: [
    {
      measurement: 'express_response_times',
      fields: {
        path: influx.FieldType.STRING,
        duration: influx.FieldType.INTEGER
      },
      tags: ['host']
    }
  ]
});

export const ExpressTimer = function(req: Request, res: Response, next: NextFunction) {
  const start = Date.now();

  res.on('finish', () => {
    const duration = Date.now() - start;

    Influx.writePoints([
      {
        measurement: 'express_response_times',
        tags: { host: os.hostname() },
        fields: { duration, path: req.path }, //path gets the red underline with the error Type 'string' is not assignable to type 'FieldType'.
        timestamp: Date.now()
      }
    ]);
  });

  return next();
};

If I change path to be a number everything works fine, but because fields has type { [name: string]: influx.FieldType } and FieldType is an enum only numbers are assignable in fields when using typescript.

This is an issue when using influx@next, in the current stable version 5.0.7 FieldMap is used instead and is a type, but this issue should be addressed in the @next version.

export declare type FieldMap = {
    [name: string]: string | number | boolean;
};

I met this issue while following the official guide https://node-influx.github.io, it looks like the guide is neglected
