Hi,

When there is a change in the redis Cluster and Tyk is still talking to a slave, it is still answering success codes although it logs errors in storing the new created key :

When a run the following command

$ curl -X PUT http://localhost:8080/tyk/keys/key_value --header “x-tyk-authorization: TYK_TOKEN” --header “Content-Type:application/json” --data ‘{
“allowance”: 1000,
“rate”: 1000,
“per”: 1,
“expires”: 0,
“quota_max”: -1,
“access_rights”: {
“1”: {}
},
“org_id”: “”
}’

I get this response as it would be working normally :
{“key”:“key_value”,“status”:“ok”,“action”:“modified”}

Here is what I get in the tyk.log :
time=“2015-08-24T12:02:58+02:00” level=warning msg=“Tracked quota reset for key: key_value”
time=“2015-08-24T12:02:58+02:00” level=info msg=“New key added or updated.” key=“key_value”
time=“2015-08-24T12:02:58+02:00” level=error msg=“Error trying to set value:”
time=“2015-08-24T12:02:58+02:00” level=error msg=“READONLY You can’t write against a read only slave.”

Is it working as expected ?

thanks in advance

Hi Pascal,

No, that should have propagated an error :frowning:

Can you raise a GH ticket?

Cheers,
Martin

Hi,

Yeah I marked mine as a dupe :wink:

Went into an issue-raising frenzy from the feedback we’ve gathered recently…

thanks for adding the ticket, will leave your as the original…

Cheers,
Martin
