TypeError with (0 , _genMapping.maybeAddMapping) is not a function

Question

I'm getting errors in the app which I cannot help myself with fixing it. What might be the reason of 2 below errors? There are similar, the root-directory of them differs.

it occurred when I started to work on react-export-table, my intention is to export data which is an array of objects into excel file. Below You can find the codesandbox which reflects the code I have in my app: https://codesandbox.io/s/nice-cannon-zohev8?file=/src/App.js

thanks a lot !

There's a similar question answered here: I'm getting the error "_genMapping.maybeAddMapping is not a function" when I try to collect coverage from jest tests

Delete the node_modules folder and re-run yarn.
(or npm install, just match what your repo normally uses)

I did not delete the lock file, just rebuilding node_modules worked for me.
