Reading group of arrays fails for some reason

Hi, I hope I'm not overseeing some basic mistake from my side, but I feel like this should work but doesn't. What works:

> z1 <- system.file("extdata", "zarr_examples", "row-first",
+                   "int32.zarr",
+                   package = "Rarr"
+ )

> zarr_overview(z1)

Type: Array
Path: /net/home/iflik/R/x86_64-pc-linux-gnu-library/4.4/Rarr/extdata/zarr_examples/row-first/int32.zarr
Shape: 30 x 20 x 10
Chunk Shape: 10 x 10 x 5
No. of Chunks: 12 (3 x 2 x 2)
Data Type: int32
Endianness: little
Compressor: blosc

> read_zarr_array(zarr_array_path = z1, index = list(1:10, 1:5, 1))
, , 1

      [,1] [,2] [,3] [,4] [,5]
 [1,]    1    2    3    4    5
 [2,]    1    0    0    0    0
 [3,]    1    0    0    0    0
 [4,]    1    0    0    0    0
 [5,]    1    0    0    0    0
 [6,]    1    0    0    0    0
 [7,]    1    0    0    0    0
 [8,]    1    0    0    0    0
 [9,]    1    0    0    0    0
[10,]    1    0    0    0    0

But with my own file the exact same works until zarr_overview() but for the exact same file path says "Error in open.connection(con, "rb") : cannot open the connection"

> z1 <- "/net/data/MODIS/MCD43C4/gapfilled-kndvi-8D-0.05deg-1x3600x7200/data/gapfilled_kndvi_2000-2023_8D_0.05deg_1x3600x7200.zarr"

Any idea why?
