Hi Ashish, Thank you for reaching out. As mentioned here, a user list can only contain members with one type of data. Based on the error you shared, it looks like the user list is already using hashed emails as the key so trying to add a member with a device ID key will fail or you are trying to upload a member with both key types which is also invalid.
If this is not the issue, please share your complete detailed request and response logs via Reply privately to author so I can further investigate the issue. You can find information on enabling logging in the ReadMe of your client library.
