Actually I'm favor of throwing if fieldToFocus doesn't exist. Checking if the value formatter can be called only solves the problem in one location, we're still prone to calling stuff from a column definition that is null. I think in v6 we should throw in

mui-x/packages/grid/x-data-grid/src/hooks/features/rows/useGridParamsApi.ts

Line 164 in efcc39e

warnMissingColumn(field);

instead of a warning.

But I'm OK with the changes from this PR.

On one hand it would be consistent with what we do, when rowId is missing.
On the other hand, the grid is still functional and throwing in production might not be the best solution.
