We use the Term Store for, mainly, on specific set of values to share across our SPO.
Starting on 03.10.2025, all of the lists that use that Term Store in their Managed Metadata fields started erroring out.
If you are creating a new form or editting an existing one, when selecting the 'tag' icon (that opens the modal selector window), the resulting value that gets inserted into the text box is '[object Object]'. This fails to save a value to the database.
We can still use intellisense to begin typing in the field and the value is selectable. Edit in Gridview also still works using intellisense OR the 'tag' button which opens a modal selector window.
I wonder if something has changed in SPO (and update on 03.10.2025 possibly?) and the Plumsail interaction is not working.
I did test a new form with NO Plumsail form created and all works well with the out-of-the-box SPO implementation of the form.
We are not doing anything with the onchange events or anything for this control. We've simply created a Managed Metadata field, added it to the Plumsail form and saved.
Is anyone else experiencing this issue?
