bug error px and % are incompatible units (grid)

[onno-timmerman]

Not sure where to go with this problem, its first time I had this kind of problem with django-sass.
in regular css this does work

I have the following line in my scss

.grid-columns {
display: grid;
grid-template-columns: repeat(auto-fit, minmax(min(200px, 100%), 1fr));
}

I get the following error:

Exception Type: | CompileError
Internal Error: Incompatible units: '%' and 'px'.

Variable | Value
_get_file_arg | <function compile.<locals>._get_file_arg at 0x1073f1ab0>
custom_functions | [<sass.SassFunction object at 0x1073a0cc0>]
