Hi All,

I am trying to create bookableresourcebooking record using offline js as follows.

function createBooking(ResourceId, ResourceName, workorderId, workorderName, bookingStatusID) {

var startDateTime = new Date();
startDateTime = startDateTime.setMinutes(startDateTime.getMinutes() - 60);
startDateTime = new Date(startDateTime);

var endDateTime = new Date();

var newBooking = new MobileCRM.DynamicEntity.createNew("bookableresourcebooking");
newBooking.properties.starttime = startDateTime;
newBooking.properties.endtime = endDateTime;
newBooking.properties.duration = 1;
newBooking.properties.bookingstatus = new MobileCRM.Reference("bookingstatus", bookingStatusID, "Scheduled");
newBooking.properties.msdyn_workorder = new MobileCRM.Reference("msdyn_workorder", workorderId, workorderName);
newBooking.properties.resource = new MobileCRM.Reference("systemuser", ResourceId, ResourceName);
newBooking.save(function (err) {
if (err != null) {

document.getElementById("error").innerHTML += "<p> " + err + " </p>";
}
else {
document.getElementById("error").innerHTML = "<p> Sucessfully created a booking </p >";
}
}
);
}

But I am geeting following error

Server Error: Length cannot be less than zero. Parameter name: length

I hope this error comes due to start time and end time (when both are equal)

I think the error might be pointing somewhere else in the code.

Are you using a parameter called 'length' anywhere?

Hi Thomas,

No. In the OOB form also getting this error when strat time and end times are equal.

Thanks

startDateTime = startDateTime.setMinutes(startDateTime.getMinutes() - 60);

Maybe its this part of the code?

Could you try putting static date times in the start and end time?

All I can think of is setting some alerts in your code and see what is being triggered.

Maybe its the BookableResourceBooking javascript that could be causing the error? Maybe creating a new booking directly in the mobile could cause it to act strange ?

Hi, I am also receiving the same error. I am setting the bookable resource booking start date with current date. Did you find a solution?

could it be due to specifying a required field?

Questions :1) have you added any logic to the forms via rules? Have you changed the OOB form or OOB logic?
2) you said you updated the offline js? Why?

I ask because I am able to create a booking in offline mode with zero issues.

Hi All,

I have found the error. This error occurs due to the wrong MobileCRM.Reference. I have used the wrong reference.

newBooking.properties.resource = new MobileCRM.Reference("systemuser", ResourceId, ResourceName); The correct entity is the bookableresorce.

Thanks
