Start with tests/inferers/test_zarr_avg_merger.py, especially test_zarr_avg_merger_patches at line 301, then inspect monai/inferers/merger.py around line 273 where ZarrAvgMerger creates its output. Run the failing test and update the Zarr array creation so it works with the reported format; done means the test passes without the ValueError.
