When the Zoho Social Login has been enabled, a client will be added for your application in the API Console. This issue will occur if the client gets deleted in the API console. To resolve this issue, you must navigate to the Social Login section under Authentication Types in the Authentication component of Catalyst CloudScale, and then disable and re-enable the Zoho Social Login.
