I am trying to run Snakemake on a SLURM cluster where accounts take the form account:subaccount. However, when I try to write the cluster config.yaml as follows,

executor: local
default-resources:
  slurm_account: account:subaccount
  slurm_partition: partition
  runtime: 120 # Walltime in minutes
  mem_mb: 10000

Snakemake crashes with the error

Error:
  WorkflowError:
    Failed to evaluate default resources value 'account:subaccount'.
        String arguments may need additional quoting. Ex: --default-resources "tmpdir='/home/user/tmp'".
    SyntaxError: invalid syntax (<string>, line 1)
Wildcards:

I have tried surrounding the account:subaccount string in any number of quotation mark combinations. What I found was that passing

executor: local
default-resources:
  slurm_account: "'account:subaccount'"
  slurm_partition: partition
  runtime: 120 # Walltime in minutes
  mem_mb: 10000

seems to work for the main Snakemake routine, but then the child jobs crash with the above error.

Is there a way for me to correctly pass the SLURM account name with the colon in it to Snakemake?
