Add-PnpFile is failed to set a column (meta) value whose data type is 'multiple lines of text'

[raffygim]

hi, all,

I am a newbie of PnP Powershell and this is my first posting.

Does anyone help me why 'Notes' column whose type is 'Multiple lines of text' is not set the value passed?
Is there anything I may check?

All other type of columns (Meta) works as I expected.
See the attached screenshot: Notes column context menu, which shows only Column Setting, while the other columns shows 'Sort/filterby etc context menu'. Is it a normal? Do you think that may be the cause for me not to set the value using below PS script Add-PnPFile, which loads up the window file, to the SP Document under Document Set.

Thank you in adavance
