Milestone task and changeTaskId not working

Hi,

I have a modified dataprocessor that allows me to send all data in a single batch.
The data are sent manually by the user.

I have a function in return of my api call that allows me to update my data in front. Everything goes well except for the ‘milestone’ tasks which, if they have a parent, return an error when I use the changeTaskId function

This is the error

Can you help me to solve this problem?

Thanks a lot

Hello Julien,
Gantt has a bug with the changeTaskId method. If you try to assign the ID of a task that already exists, you will get the error message.
But the error message is different, so, probably, it may not be related to the Data Processor.

It is hard to suggest what might be wrong as I don’t see your configuration and what you changed in the function. Please, send me a snippet where the issue can be reproduced.
