Compilation error

[rotor-58]

Hello!
i'm new here and also new in developing PowerBI visualizations. i've tried installing and running the Gantt-chart visualization, but i'm getting the same errors as mentioned by @smilekudo in this link, viz., the ones with textMeasurementService and textProperties:

#198 (comment)

here's my message log from powershell:

i managed to resolve the error with textMasurementService by modifying the line in the index.d.ts file from:

import { textMeasurementService } from "./textMeasurementService";

to:

import * as textMeasurementService from "./textMeasurementService";

but how do i fix the error with the textProperties?
From what i've understood so far, the parameter textProperties is used within individual methods but is never returned. should that be added here?

please help. thanks in advance! :)
