What's this error mean while creating a task in fusion via custom api module.

[DestPr]

I'm getting this error message - [428] We're sorry, but your save failed because someone else tried to save this project at the same time. Please try to save again.

For context I'm creating a task using custom api module see attached image. I have iterating value which is getting added as a suffix to the task name. For example if I have 3 values, three task(with value suffix) should be created but two task are getting created and I'm getting this runtime error.

suggestion needed to fix the issue.

Custom api module output

iterator value

Hi @DestPr 

As with your last question I can't tell because I don't see the module configuration nor the flow of the modules. 

If you repeatedly get this same error please provide more info so we can troubleshoot.

Hi @Sven-iX, 

Below is my full workflow - 

The Steps are 1>trigger is related to changes in task as language field get updated or newly added.

2> The read records module are there to get some data about Project and Custom form.

3>The iterator is there to pass the value as a suffix while creating task.

4> The main module is create product combination module used to create task. here is the configuration of it.

The problem is as above that when I'm adding 3 values I should get 3 tasks but 2 tasks are getting created or sometimes just one task is generated, followed by that error which i mentioned.

I think description is pretty clear, action was not completed because there was parallel action happening on the project. I would just re-try, e.g. with error handler.
If I get this type of error in incomplete executions I usually don't have issues with re-running them successfully
