Error reading uo file

Error in untitled (line 52)

u1 = ncread(fullfile(filename,'uo'),[1 1 nz 1],[length(lon) length(lat) 1 ntime]);

for yi=1:nyear
    ny=ystart+yi-1
    filename=fullfile(fp,['June' num2str(ny) '.nc']);
    u1 = ncread(fullfile(filename,'uo'),[1 1 nz 1],[length(lon) length(lat) 1 ntime]);
    v1 = ncread(fullfile(filename,'uo'),[1 1 nz 1],[length(lon) length(lat) 1 ntime])
    
    % if you want monthly averages, do this
    % note this will end up a different dimension if you're extracting
    % multiple layers
    % might want to predefine these matrices depending on what you want
    % https://uk.mathworks.com/help/matlab/ref/mean.html
    u2(:,:,yi)=mean(u1,[4]); whos u2
    v2(:,:,yi)=mean(v1,[4]);
    
end

% then take the mean to get the mean over all the years, for one depth
% layer only, remember
u3=mean(u2,[3]); %taking the mean over the third dimension
v3=mean(u2,[3]);

% calculate the magnitude of the vel and plot
uv4=sqrt(u3.^2+v3.^2);

close all, pcolor(LON,LAT,uv4.'), shading flat, colorbar

u1 = ncread(filename,'uo',[1 1 nz 1],[length(lon) length(lat) 1 ntime]);
v1 = ncread(filename,'uo',[1 1 nz 1],[length(lon) length(lat) 1 ntime]);

try without using fullfile and extra parenthesis

I still get the same error, this is the full error.

Error using matlab.internal.imagesci.netcdflib

The NetCDF library encountered an error during execution of 'getVarsFloat' function - 'Start+count

exceeds dimension bound (NC_EEDGE)'.

Error in netcdf.getVar (line 205)

data = matlab.internal.imagesci.netcdflib(funcstr,ncid,varid,varargin{:});

Error in internal.matlab.imagesci.nc/read (line 690)

data = netcdf.getVar(gid, varid, ...

Error in ncread (line 76)

See the above question / answer which discusses similar issue, I think its related with Version and /or file limit contents

I altered my data, as it was a typo and teh variables should have been uo and vo for u1 and v1, but I get the same error.
