EventbriteSync not working with Salesforce

[Apoorv Sharma]

Hello,

We are facing issue while using bulk import of events from Eventbrite to Salesforce using the EventbriteSync managed package. If the import is done by providing single Eventbrite event id then it's working fine but while doing a bulk import the following error shows in the integration log.

OAuth token: No valid OAuth token

HTTP 401 UNAUTHORIZEDAccess-Control-Max-Age: 600
Vary: Accept
Allow: GET, HEAD, OPTIONS
Access-Control-Allow-Origin: *
Access-Control-Allow-Headers: Authorization, Content-Type, Eventbrite-API-Waypoint-Token, Eventbrite-API-Deprecated-Features
Content-Type: text/html; charset=utf-8

{
"status_code": 401,
"error_description": "An OAuth token is required for all requests",
"error": "NO_AUTH"
}

Any and all help would be appreciated.

Thank you
