Answer 1

Hi @Rene Pally ,
This appears to be a duplicate of this recent GitHub issue: https://github.com/OfficeDev/office-js/issues/2120. Does the workaround given in that thread help?

For this example, it would be streamlining the code to something like this:

   let firstTable = context.document.body.tables.getFirst();  
   let firstCell = firstTable.getCell(0, 0).body;  
   firstTable.autoFitWindow();  
   await context.sync();

Works, thanks!
