Sometimes the console blows up this error:

GraphQL Error Unknown argument `formatString`

A temporary workaround to solve this problem is to delete .cache folder and rerun your desired build task again.

Hey @diegonvs, any update with this issue? after delete .cache folder, I still can reproduce the issue :(
