What is Redis WRONGTYPE Operation against a key holding the wrong kind of value

Identify the key causing the error by noting the key mentioned in your command or error message.Run TYPE yourkey to determine the actual type of the problematic key.Compare the expected type for your operation with the actual type returned by the TYPE command to understand the mismatch.If the value type of the key is indeed incorrect for your intended operation, decide on the necessary action:If the data is no longer needed or can be safely replaced, delete the key using DEL yourkey and then proceed with your operation.If the data is important, consider renaming the key using RENAME yourkey newkey for backup or further investigation, and then proceed with your original operation by setting the correct type for yourkey.After resolving the type mismatch, rerun your original command to confirm the error is resolved.
