this will not work for private attributes about cleanenv

[kz]

I ran into this problem too, and I notice Kelsey Hightower's envconfig package also does not check whether the field you are attempting to set is unexported. Assuming there is no other case where a developer would set the env tag on an unexported field other than intending for that field to be exported, should unexported fields with env tags throw errors?

This is a standard and expected behavior of Golang - library cannot read unexported fields from another package.

The expected behavior it that such fields will be ignored.

It doesn't skip unexport field

@838239178 can you provide a code example, please?

Better create a new issue with an example and detailed error and environment description. Thanks
