Error in resultIncreased(history) : No isotopes have been detected, peak picking not optimizable by IPO! #74

I used the official code and it ran successfully, but it didn't work when I switched to the cdf file I used for my experiment. Earlier I asked the developers at xcms that they might have some problems with xcmsSet, so I'm not sure it's me now. The problem with the cdf file is still a problem with the IPO package or there is still a problem with xcms. The following is my error message:
