Hello @alpana2712,
According to your logs the errors comes from a non JSON response sent by the Zendesk API.
The connectors tries to deserialize JSON payload but fails because the response does not contain JSON.
This is probably because you hit the rate limit of the Zendesk API and the connectors does not well manage the error response.
Could you please file a bug report on our GitHub repo to share this problem with our connector team?
To check if it’s a problem related rate limiting Could you also please try with a more recent start_date parameter in your source configuration (e.g 2022-03-29).
