Transposition function doesn't work after build in react app

Hello, I use opensheetmusicdisplay for my react application. I have an error when i use transposition function when app is builded “npm run build”. But it works in developement mode “npm run start”

this.osmd.updateGraphic()

• in chromium browser

• in Firefox […] VexFlowMusicSheetDrawer.drawMeasure TypeError: u is undefined

// ...
this.osmd = new OSMD(this.divRef.current, this.osmdOptions)
this.osmd.TransposeCalculator = new TransposeCalculator()
// ...
transpose (value = 0) {
    this.osmd.Sheet.Transpose = parseInt(value)
    this.osmd.updateGraphic()
    this.osmd.render()
}

I don’t know why it doesn’t works after build ?

Hi, did you tried to import it directly?

import {
  OpenSheetMusicDisplay as OSMD,
  TransposeCalculator,
} from "opensheetmusicdisplay";

works for me.

@fedwiiix Have you tried it with OSMD 1.3.0? It should work. It works in the plain javascript example project even without the plugin build: https://github.com/opensheetmusicdisplay/RawJavascript-usage-example/blob/master/indexSimpler.html

Closing for now, but can reopen if the problem persists.
