first time this happened to me:

> Peaks_TSS_all_hgnc<- getBM(filters= "ensembl_transcript_id", attributes=c("ensembl_transcript_id","ensembl_gene_id","hgnc_symbol"),values=Peaks_TSS_all$ClosestTSS_ID,mart= mart)
Batch submitting query [=============================>-]  95% eta:  2mError in getBM(filters = "ensembl_transcript_id", attributes = c("ensembl_transcript_id",  : 
  The query to the BioMart webservice returned an invalid result: biomaRt expected a character string of length 1.

The first thing you need to do is rectify this situation ----> R version 3.6.3 (2020-02-29)

You are 1.5 years out of date, and I believe Mike Smith has made many improvements in the intervening period. Plus, we don't support old versions (it's enough to support the current release), so unless you get the same error on the current release, nobody is going to provide help anyway, other than to say you should update. So you should update.
