fmriprep: singularity build 1.3.1 fails immediately

Looks like there are some issues with the 1.3.1 build in singularity. I get a TemplateFlow warning and a bunch of DeprecationWarnings as soon as I submit. The standard output shows that BIDS compliance was checked, but there’s nothing else in the log. The error log is below. My system has singularity v. 2.6.1.
