Hi Baptiste

I tried the method UpdateTask() with the following parameters:

// Build update data
object[] updateData = new object[]
{
new object[]
{
new string[] // general info
{
schedulerTask.Id.ToString(), // [0] : task ID
null, ////taskName, // [1] : name
null, ////activStartDay, // [2] : start date (YYYY-MM-DD) (leave empty to have start time == current time)
null, ////activStopDay, // [3] : end date (YYYY-MM-DD) (can be left empty)
null, ////startTime, // [4] : start run time (HH:MM)
null, ////taskType, // [5] : task type (daily / monthly / weekly / once)
null, ////runInterval, // [6] : run interval (x minutes / 1,…,31,101,102 / 1,3,5,7 (1=monday, 7=sunday)) (101-112 -> months)
null, ////””, // [7] : # of repeats before final actions are executed
null, ////taskDescription, // [8] : description
input.Enable.ToString().ToUpper(), // [9] : enabled (TRUE/FALSE)
null, ////endTime, // [10] : end run time (HH:MM) (only affects daily tasks)
null ////””, // [11]: minutes interval for weekly/monthly tasks either an enddate or a repeat count should be specified
},
},

new object[] // repeat actions
{
//new string[]
//{
// “automation”, // action type
// scriptName, // name of automation script
// elemLinked, // example of linking element 123/456 to script dummy 1
// paramLinked, // … other options & further linking of dummies to elements can be added
// // elem2Linked,
// “CHECKSETS:FALSE”,
// “DEFER:False”, // run sync
//}
},
new object[] { } // final actions
};

// send update command
int returnValue = dma.Scheduler.UpdateTask(updateData);

This gives me the following error:
An exception occurred:
System.Runtime.InteropServices.COMException (0x80004005): Error HRESULT E_FAIL has been returned from a call to a COM component.

I also checked the logs on the DMA for the Scheduler and this is wat I got:
2023/03/15 17:47:29.555|SLScheduler.exe 10.3.2301.1186|12012|13120|CBase::UpdateTask|DBG|-1|Task info not found for task 1.

Any clues on how to further debug or who to contact?

Thanks in advance!
