error in RuptureContext for some sources with parameter 'occurrence_rate'

The following error is given by a model using one sites.csv, but runs correctly for a different sites.csv. I will share the job files privately.

AttributeError:

On which machine does this happen? It could be an outdated cluster.

It happened on Hendrix as well as my own computer
