Issue
Scheduled subscriptions are failing with the error below:
SubscriptionErrorResult: ErrorCode: 150024; Error Category: UNKNOWN; Error message: SUBSCRIPTION_UNKNOWN_ERROR. For input string: "true";Internal Server Error
Last Modified Date: 15 Jun 2023
Environment
- Tableau Server 2022.3.1
- CentOS 7
- MS Exchange
Resolution
Run the following tsm command on Tableau Server to verify the value set for "subscriptions.max_attachment_size_megabytes" (Default value is 150 (in MB)).
- tsm configuration get -k subscriptions.max_attachment_size_megabytes (It will give the current value set for the 'subscriptions.max_attachment_size_megabytes' parameter, if it is set to 'true' then run following commands)
- tsm configuration set -k subscriptions.max_attachment_size_megabytes -v 150
- tsm pending-changes apply (you must run this command, it will require a Tableau server restart, command will display a prompt to let you know a restart will occur)
Once the Tableau server is up & running again, please run a subscription manually and verify if the emails are now triggering correctly.
Cause
By mistake, the boolean value (true) was set but it should be a numerical value for subscriptions.max_attachment_size_megabytes.Additional Information
