it looks like your input format is not right. it complains about lfcSE. You may remove the header and try it again.

Here is how the rnk file must look: https://software.broadinstitute.org/cancer/software/gsea/wiki/index.php/Data_formats#RNK:_Ranked_list_file_format_.28.2A.rnk.29

lfcSE is a name from DESeq2 results, so you're probably providing the wrong data (format).
