When i read DFS2 file overflow error happened. (ArgumentError: argument 2: <class 'OverflowError'>: int too long to convert)
I am using latest mikeio version.

This is the first time I have sen this with a Dfs2 file.

Can you provide some additional info on which tool/engine that produced the file and the dimensions and a few screenshots from Mike zero with item info, dimensions, spatial axis info etc.

[amit-ramboll]

DFS2 files produced from MIKE SHE.
Please see attached images.

Please find the sample file from that link.

what is the issue, in file or any python library?

[ecomodeller]

The problem is in the decoding it in python.

You can try to use an older version MIKE IO v 0.6.4 which is based on the .NET SDK, and see if this is any different, until @JesperGr have time to look at this file.

pip install mikeio==0.6.4

I did try today to reproduce this issue. But I could not. It works all fine to call

'dfs2File = DfsFileFactory.Dfs2FileOpen('BalEge_Ref_2DSZ.dfs2')'

Can you please try with the lastest version of mikeio to see if the problem is still there.

There was a fix on August 27 2021 stating "Fixing reading and writing encoding keys, used by most dfs3 files.". I am suspecting that mikeio did not include that fix at that point in time.
