This exception is thrown when you try to perform an operation on a Redis key with the wrong type of value. For example, if you try to perform a string operation on a key that holds a hash value or a set operation on a key that holds a string value, this exception will be thrown.
To fix this issue, you need to ensure that you are using the correct Redis data type for your key. You can check the current data type of a key using the Redis command "TYPE key". Once you have identified the correct data type for your key, you can update it using the appropriate Redis command.
For example, if you have a key that should hold a string value but is currently holding a hash value, you can update it using the Redis command "SET key value". This will overwrite the existing hash value with the new string value.
It is important to note that changing the data type of a key will also remove any existing data associated with that key. So, make sure to take a backup of your data before making any changes to your Redis database.
