WRONGTYPE - Key with colons

[george-mengelberg]

Hello,
I am encountering WRONGKEY errors under the following circumstances:

• redis-cli trying to read keys added by redis-py (key = 'frontend:test.ufam.jp')
• redis-py client trying to read keys added by redis-cli (key = 'frontend:test.ufam.jp')

Each client is able to successfully read keys they created. Here is a simplified example showing a call to keys() then using the value in a call to lrange() which causes an error.

Any suggestions or insight as to what may be going wrong would be much appreciated.

Environment:

• Ubuntu: Ubuntu 16.04.1 LTS
• Python Redis version: redis (2.10.5)
• redis-server: 3:3.0.7-1chl1~precise1

WRONGKEY indicates that you tried to to perform an operation on a value of a different type. In your example, it looks like you're trying to perform the list operation LRANGE on a key, but the error indicates that the value stored at that key isn't a Redis list.

You are correct sir. Thank you for your response.

In your example you're using Python's builtin type() on the key name which will always be a string. To see the same value that redis-cli shows you'd want to use r.type(keyname) instead.
