Sharepoint Task with custom content type

[AndrewLansford]

I have a sharepoint task list - Sharepoint Online that I created using the "Tasks" app.

I have added an additional content type to the list to store some custom content that I want to manage along with the task.

I would like to update the list item in Flow. I can type the list name as a custom value and Flow smartly pulls in the field names associated with all content types. Configure the Update Sharepoint Item action in flow and everything looks great.

But the flow run fails with the following message:

InvalidTemplate. Unable to process template language expressions in action 'Update_item' inputs at line '1' and column '2515': 'The template language expression 'items('Apply_to_each_newly_created_it')['Task Name']' cannot be evaluated because property 'Task Name' doesn't exist, available properties are '@odata.etag, ItemInternalId, ID, Title, Checkmark, AssignedTo, AssignedTo@odata.type, AssignedTo#Claims, AssignedTo#Claims@odata.type, Average_x0020_Days_x0020_Between, Last_x0020_Order, Out_x0020_of_x0020_Pattern, Salesman_x0020_Code, Stage, Stage#Id, Standard_x0020_Deviation_x0020_D, Total_x0020_Order_x0020_Volume, Predecessors, Predecessors@odata.type, Predecessors#Id, Predecessors#Id@odata.type, Priority, Priority#Id, Status, Status#Id, PercentComplete, Reason_x0020_Category, Reason_x0020_Category#Id, Modified, Created, Author, Author#Claims, Editor, Editor#Claims, {Identifier}, {IsFolder}, {Link}, {Name}, {FilenameWithExtension}, {Path}, {ContentType}, {ContentType}#Id, {HasAttachments}'. Please see https://aka.ms/logicexpressions for usage details.'.

This is particularly challenging, because I can't change which column flow is trying to update. I believe that it is because the list was created as a Task app, which defaults the "Title" column to the name "Task Name".

I believe that flow should have the template language expression be:

'items('Apply_to_each_newly_created_it')['Title']'

But I have no way to force it to do so.

Any suggestions?

Hi @AndrewLansford,

Could you share a screenshot of your flow?

It seems that you have added an additional content type to the list, what are the columns contained in the list?

The error message says that the property “Task Name” doesn’t exist. Please make sure it does contain a column “Task Name”.

I have created a simple flow likes below which works fine. Task name does exist in the list.

Best regards,

Mabel

This is the screenshot of the update item. You can see that the list has been identified as having a "Task Name" property by flow.

The sharepoint list column definitions below definitely show a column named "Task Name".

Hi @AndrewLansford,

Thanks for updating.

It seems that Task name field is being used in Out of Pattern Customer Report and Task. Please try to remove it from the content type Out Of Pattern Customer to see if it will work.

Please share a full screenshot of your flow to help reproduce it on my side.

Best regards,

Mabel

Ok. I think I figured this one out.

The content type "Out of Pattern Customer Report" was inheriting from the type "Item", which has the first property as "Title".

I recreated the content type, but instead inherited from the content type "Task".

This allowed me to delete the "Task" content type from the list after adding the "Out of Pattern Customer Report".

Screenshot of the list columns setup below.
