We have installed Twilio App for Salesforce and configured it. The 1 to 1 Contact message is working fine, while Bulk SMS to Campaign Member is showing Internal Server error as below:

Error ID: 1754947416-96315 (119852647)

Checked debuglog too but didn't find anything.l

  • Didn't mean to save the duplicate, but essentially, the answer to this post boils down to - you have to contact Salesforce Support. You have run into a gack and no one on this site will be able to help you here. – Adrian Larson Jun 10 '19 at 19:12
  • Ok, Actaully I reached to Twilio support which package application we are using. And they recommended me to post a question here to get a solution faster. – Tarun Jain Jun 11 '19 at 20:23
  • Given that the error is a gack, that advice was not very well grounded. Much better to reach out to Salesforce directly. – Adrian Larson Jun 11 '19 at 21:05
