xarray is trying to overwrite indexes for the `bnds` dimension but there are no indexes associated with that dimension. As a work around, you can assign values for `bnds`: `ds1[""bnds""] = [0,1]` and `ds2[""bnds""] = [0,1]` and then use `join=""override""`","{""total_count"": 1, ""+1"": 1, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,548029687

ds3 = xr.concat([ds1,ds2], dim='time', join='left')

Are they *completely* identical? I see you've used `np.allclose` to assert that they are identical rather than `np.array_equal`. You might want to try `concat` with `compat='override'`?","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,548029687
