Share_folder endpoint returning too_many_mounts/tree_size_exceeded

An operation that worked perfectly fine before now returns the following error:

makeDropboxRequest: https://api.dropboxapi.com/2/sharing/share_folder
Error making Dropbox request: too_many_mounts/tree_size_exceeded/
Network error making request to https://api.dropboxapi.com/2/sharing/share_folder: Error: too_many_mounts/tree_size_exceeded/

The process leading up to this error:

1-4 subfolders are created, of which the parent (main) folder housing those 4 subfolders is shared so that groups can be assigned to have access to it. Other than that the folder is empty, and the subfolders are empty as well.

This never happened before, so I'd like to know what changed so that we can apply a workaround.

    I understand you're using the Dropbox API to create shared folders in an account and are receiving a 'too_many_mounts/tree_size_exceeded' error. This is a limit on the number of "mounts" in a folder tree. On Dropbox, "mounts" include both team folders and shared folders. Sharing a folder in an account creates a new mount, so because of the very large number of existing mounts in the filesystem, this error will be triggered when you attempt to make more. There isn't an option for bypassing this limit, so you would need to reduce the number of shared/team folders in the folder tree, or use a different folder tree or account without that many mounts in it.

      So what is the intended solution if we want to create shared folders and assign groups to them? Permanently deleting folders is not an option. We create 3-4 folders per project and we do around 1500 projects a year, every folder needs to be a shared folder otherwise we can not assign groups to access them based on the project requirements.

        Unfortunately there isn't an option for removing or bypassing this limit; to avoid this error, you'd need to bring the number below the limit, or use a different folder tree/account.
