SharePoint Error when trying to create a list from an existing list that has a Form created for it

Tanner Holtz 0

I'm currently running into the following error when I try to create a list from an existing list in SharePoint:

Action 1 (createSPList) is invalid. List subaction 29 (addSPView) is invalid. Parameter name has an invalid value.

The list I'm trying to copy has 20+ columns with most being Yes/No choice columns that are set Green and Red respectively. The rest of the columns are single lines of text. This list also has a form created to fill in these columns. I have 10 other Lists on the same SharePoint site all setup the same way and none of them are having this issue when trying to create a new list from an existing list.

So far, I have tried recreating the List from a CSV file of the old list and that worked but as soon as I add a form to the new list the error returns. If I delete the form, I'm once again able to create a new list from the existing list.

Has anyone found a fix for this issue? Deleting the form before creating a copy of the new list works for now but remaking the form is annoying when I know I shouldn't have to.

Hi Tanner,

Based on your sharing, the error message List subaction 29 (addSPView) is invalid. Parameter name has an invalid value. means SharePoint generated an addSPView operation with a missing, unsupported, or otherwise invalid view name. Since the issue begins immediately after adding a Lists form, I suspect the metadata that the "From existing list" provisioning process is incorrectly treated as a conventional SharePoint view. That said, this could be a SharePoint Online service defect or unsupported interaction between Lists forms and list duplication.

For you to receive the best possible assistance in this case, I highly recommend contact your company's IT department and ask your administrator to create a support ticket through the Microsoft 365 admin center for further investigation. This route ensures you can contact a technical support engineer, who can perform a remote session to investigate the situation, verify the backend configurations, and run any necessary synchronization tools to resolve the problem. If the issue requires further attention, they can escalate it to a specialized team for deeper analysis.
