Consider a workbook with a table and a dynamic array formula in column 3 e.g. a =HYPERLINK() formula based on the value of column 1 and 2.
When adding values for the first 2 columns in desktop or web, table gets automatically expanded and column 3 shows the hyperlink.
However doing the same through the Graph API returns The number of rows or columns in the input array doesn't match the size or dimensions of the range. Basically, the API requires all values to be passed including column 3, which supersedes/overwrites the array formula.
