I created the following ticket: https://github.com/elastacloud/parquet-dotnet/issues/429
Let's see if someone can take a look.

As replied by the parquet.net owner: https://github.com/elastacloud/parquet-dotnet/issues/429
It seems the parquet file is not valid as per even the native Java standards. So not much can be done on our side for this. I'm closing this ticket as fixed as the original issue has been fixed.

I am also experiencing this issue

The application is still using the old v1 Parquet.Net library which does not support many complicated parquet files. I will look into updating to the latest version but this will require a major re-write as the newer versions have changed dramatically.

Please try the new beta release: https://github.com/mukunku/ParquetViewer/releases/tag/v2.0
I was able to load the above parquet file using this new version. Keep in mind that this is a beta release so all the features have not been fully tested.

I am now getting a different error message after clicking done on this UI:
If necessary I can provide a sample file for testing.

Absolutely. I have generated a sample of random data using a library called "parquetjs".
And here is the sample file in a ZIP archive:

Seems like Parquet.NET has issues opening these files. I took a look at ParquetJS and looks like the data types are not standard, at least as far as I can tell.
Unfortunately there isn't much I can do at this time unless the issue is resolved in the Parquet.Net library: https://github.com/elastacloud/parquet-dotnet
You can open a ticket with the Parquet.Net library if you'd like. Or if it's okay to share your sample file I can open the ticket for you.
