Android Studio MediaStore Storage can't access the folder

Issue

When trying to download and save a file, it throws an error

Primary directory file not allowed for content://media/external/downloads;
allowed directories are [Download]

How can I fix it, maybe there is no permission?

778 line, this is

val uri = resolver.insert(
                            MediaStore.Downloads.EXTERNAL_CONTENT_URI,
                            contentValues
                        )

It seems that all the necessary permissions are used in the project, so I don't even know which way to look to solve this problem

Solution

use:

put(MediaStore.DownloadColumns.RELATIVE_PATH, "Download/Peshkariki")

instead of

put(MediaStore.DownloadColumns.RELATIVE_PATH, "file/Peshkariki")

Primary directory file not allowed
