Issue with Project schedule APIs with OperationSet in latest PO version

(0) ShareShare
ReportReport
Posted on by 75

Hi,

We have faced issue on schedule API. Schedule APIs are failed for following operations on tasks:  

  • msdyn_PssDeleteV1
  • msdyn_PssUpdateV1

Exception: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.

Is anybody face same issue? Is there any workaround on schedule api issue?

Thanks

    Hi Vikas,

    We were having the same issue and once updating the Microsoft Dynamics 365 Project Operations (Dynamics 365 apps) to version 4.12.0.148 fixed the issue.  

    If you have just a Power Apps environment with Microsoft Project Service Core (Dynamics 365 apps), upgrading to version 1.0.12.148 fixes the issue as well.

    Hello Tae,

    Thanks for your response, however new upgrade version (1.0.12.148) is not available for us in admin powerapps.

    Hi Vikas,

    Not sure exactly when that version will be available in your environment as I cannot find any release notes around it.

    This same issue was fixed in the 4.12.0.148 version for Project Operations, which is the July 2021 update (docs.microsoft.com/.../whats-new-july-2021-resource-based) so hopefully, that version you are after will be rolled out soon as well.
