generic.concat (keep = average) :: bug

[daniel-caichac-DHI]

Describe the bug
Hi.

I have 2 dfs2 files, hourly data, overlap by at least 80% of the time.
I can do mikeio.generic.concat(files, keep = 'first') and it works
also mikeio.generic.concat(files, keep = 'last') and it works
but when I do
mikeio.generic.concat(files, keep = 'average') I get this error

I am certain that there is no gap in time :(

To Reproduce
mikeio.generic.concat(files, keep = 'average')

Include code snippet

Expected behavior
Concat.

I have been trying to manually set the values of my mikeio.Datarray with a custom averaging function but it keeps not-working :)
Let me try to find the bug
