I successfully ran this command several days ago, but am now having problems that sound like the same thing reported in this issue: possible Rtracklayer issue: TxDb errors in GenomicFeatures package-- cannot load TxDb with standard params from UCSC (issue began last night)

Get UCSC ensGene annotations.

Error in names(trackIds) <- sub("^ ", "", nms[nms != "new"]) :
  'names' attribute [210] must be the same length as the vector [209]
In addition: Warning message:
In riboSeqFromBAM(listInputBam, genomeName = "hg19") :
  paramScanBAM parameter is not a ScanBamParam object. Set to default NULL value!

The code described in that previous post also results in the error:

This has been fixed in devel and release (1.40.1) thanks to Jim McDonald. I put in a more robust (hopefully) heuristic in 1.40.2.

This error has to do with an internal function called trackNames that gets all the track names from UCSC when getting all the supportedUCSCtables (see your traceback output). This was fixed last Friday, and if you update to a current version of R and Bioconductor (R-3.5.0 and Bioc 3.7), you won't have any problems.

You're parsing our HTML???? This is ... crazy. This means that your parser breaks each time we make the smallest change in our html. We have a public SQL server for this purpose and are happy to help with setting up the queries in the right way.

As far as I know, we haven't changed the refGene table, I think we have never changed since they were released, to avoid problems like this. Could it be something that has to do with a Mysql server update? Do you know the exact Mysql query that is run?
