"Add to Webinar" Button Error
I get a developer error when I use the add to Webinar button on a Lead or Contact in Salesforce. The error is due to the character limit for the participants field in the Zoom External Meeting object.
When I press “Invite” error says: Insert failed. First exception on row 0; first error: STRING_TOO_LONG, External Key: data value too large: *********** (max length=50): [zoom_app__External_key__c]
When I press “Register” the error says: Argument cannot be null.
Do you know how I could solve this issue?
