Task processing failure notification templatization

Notification subject and message fields support templatization. The list of available templatization parameters depends on the template type. See the available types and parameters below:

Available template parameters:

• taskType - the task type, e.g. 'telemetry deletion';
• taskDescription - the task description, e.g. 'telemetry deletion for device c4d93dc0-63a1-11ee-aa6d-f7cbc0a71325';
• error - the error stacktrace
• tenantId - the tenant id;
• entityType - the type of the entity to which the task is related;
• entityId - the id of the entity to which the task is related;
• attempt - the number of attempts processing the task

Parameter names must be wrapped using ${...}. For example: ${entityType}. You may also modify the value of the parameter with one of the suffixes:

• upperCase, for example - ${entityType:upperCase}
• lowerCase, for example - ${entityType:lowerCase}
• capitalize, for example - ${entityType:capitalize}

Examples

Let's assume that telemetry deletion failed for some device. The following template:

Failed to process ${taskType} for ${entityType:lowerCase} ${entityId}
{:copy-code}

will be transformed to:

Failed to process telemetry deletion for device c4d93dc0-63a1-11ee-aa6d-f7cbc0a71325
