XCMS online Feature Detection Failed

Hello all,
  I am running a pairwise job through XCMS online with single sample on each dataset. I am getting "Feature detection failed" error when using the centwave method. The dataset are high resolution centroided data centroided using our in-house centroiding software. The centwave parameters that I used are
ppm  10
minimum peak width  10
maximum peak width  60
mzdiff  0.01
s/n threshold  6
integration method  (1 or 2)
prefilter peaks  3
prefilter intensity  100
noise filter  0
However when I run XCMS in R with same parameters for feature detection, it gives me 69 features with no error.
xs <- xcmsSet(files,method="centWave",snthresh=6,ppm=10,peakwidth=c(10,60),mzdiff=0.01,integrate=1,prefilter=c(3,100),noise=0)
R version 3.1.1
XCMS version 1.40

Why does XCMS online fail when R XCMS ran successfully?

Thanks
