io_fesom_file.F90 can not find dimension with size 0

I've been trying to get TCO319-BOLD running for Nils Hutter and GEOMAR.

I am faced with the following error:

1795:  error in line          525 io_fesom_file.F90 can not find dimension with size           0
2177:  error in line          525 io_fesom_file.F90 can not find dimension with size           0
 385:  error in line          525 io_fesom_file.F90 can not find dimension with size           0

The line in question: https://github.com/FESOM/fesom2/blob/2c049ce5335c368f67249216cbb3dcca236f2241/src/io_fesom_file.F90#L515-L527

Anyone got an idea what's causing this?

I found I can activate/deactivate this error by turning on / off dynamic backscatter:

    add_namelist_changes:
        namelist.dyn:
            dynamics_visc:
                opt_visc: 8

Default opt_visc: 7
