Redis ERR hash value is not a string

What is Redis ERR hash value is not a string

Verify the command that triggered the error to ensure you are not mistakenly treating a non-string value as a string. For example, if you ran GET on a hash key instead of using HGET for a specific field, correct it.Use TYPE <key> command to check the data type of the key you are trying to access. This will confirm if the key is indeed a hash or some other data type.If the key is supposed to be a hash and the command was correct, inspect the contents of the key using HGETALL <key> (if it's expected to be small) to understand its current structure and values.Review recent changes or commands applied to the Redis instance that may have inadvertently altered the key's type or value.Check for scripts or applications that interact with this Redis key and ensure they handle data types correctly, especially if they perform operations that might change the key's type (like SET used on a hash key).Monitor Redis logs for any warnings or errors that occurred around the time the issue was noticed, which might give clues on what operation caused the problem.
