Unable to export when using 'Sequence.exportAsMediaDirect()'. response: 'Error: Unknown Error'

[Pieter-Jan295492363up6]

Hey, 

I'm trying to export a sequence automaticly to a .mp4-file with 'Sequence.exportAsMediaDirect()'-method. But I get 'Error: Unknown Error' as response. I don't get more explanation from the error, so I don't know where to search for the solution. From the debugger I get the response: 'Eval Result [premierepro-23.0 (NewWorld)]: Undefined'. The code I use is the following: 

var seq = app.project.activeSequence;

var Export_Media_Pad = "C:/Users/Gebruiker/Desktop/Test_Auto_Export_PremPro/ProductVideo_Export_extendScript.mp4";

var Export_Preset_File = "C:/Program Files/Adobe/Adobe Premiere Pro 2023/Settings/IngestPresets/Transcode/Match Source - H.264 High Bitrate.epr";

var result = seq.exportAsMediaDirect(Export_Media_Pad, Export_Preset_File, 0);

$.writeln(result);

Premiere Pro version: 23.5.0 (Build S6)

My operating system: Windows 10.0.19045

System Info:

CPU: AMD Ryzen 5 3600X

GPU: Radeon RX 570 Series

RAM: 32 GB

In the attachment you can find the project I am trying to export toe .mp4 file.

Hi, I'm experiencing the same issue on Windows.
However, it works fine on Mac with Premiere Pro version 23.0.0.

@Pieter-Jan295492363up6 , how did you manage to resolve it?
In short, when using exportAsMediaDirect on Mac, it works, but on Windows, I encounter an Unknown error.

Hey, 

This problem occurred months ago for me, and it was one of the many error messages I had to resolve while writing my program 😄 Eventually, I wrote it in Python (the main code is in Python), and the piece of code that works looks like this. Hope this helps:

    Export_Preset_File = r"C:\Program Files\Adobe\Adobe Premiere Pro 2023\Settings\IngestPresets\Transcode\Match Source - H.264 High Bitrate.epr"

    project.save()

    try:

        sequence.exportAsMediaDirect(

            output_map, Export_Preset_File, pymiere.objects.app.encoder.ENCODE_IN_TO_OUT)

    except Exception as e:

        Print_Error_Functie("FOUT:", str(e))

    else:

        print (f"Export succesvol naar:   {output_map}")

Hi, many thanks. Does it mean if not save the project before export it fails with an error? Or does changing language from js to python solve your problem?
