  A similar error [has been described in the past](https://groups.google.com/g/gsea-help/c/VZzpOlbl5Ow?pli=1) and attributed to the presence of missing observations in the data.
  
  Have you checked your data and tried to look for e.g. `NA` values? It seems that GSEA does not work with missing data.
