[Excel Beta Channel] Office.js function assigns a value from one table to another table

Hello,

I am building an Excel add-in that was generated with yeoman and being edited with VS Code.

I am currently trying to read in data from one cell in a table and assign that value to a variable.
Then use that variable to assign the value to a different cell in a different table.

However my code seems to fail after any attempt of loading and syncing the table to the variable.
I had success with assigning the final cell with a hardcoded value. But it fails when replacing the hardcoded value with the variable.

Any help would be appreciated. Please find attached a code snipet and excel doc with basic data for example.
