Dear developers,  
I posted on github, but got directed to this page.  
I’m trying to install on a HPC:

- **OS** : Oracle Linux (Red Hat) 8.6
- **installation method** : `conda create -y -p ${TARGETDIR} -c conda-forge -c bioconda -c biobakery "biobakery_workflows=3.0.0a7"`
- **postinstall** : I downloaded `kneaddata` databases with `kneaddata_database` command

I tried to execute with the example data form this repository:

```auto
biobakery_workflows wmgx \
        --input biobakery_workflows/examples/wmgx/paired \
        --output outdir \
        --bypass-strain-profiling

```

but always I get this error:

```auto
Traceback (most recent call last):

TypeError: object of type 'dict_keyiterator' has no len()

```

I don’t know how to troubleshoot. Any direction, hint or idea would be welcome.  
I couldn’t find any related issues [here](https://github.com/biobakery/biobakery_workflows/issues), on the [anadama2 github page](https://github.com/biobakery/anadama2/issues) or the [biobakery forum](https://forum.biobakery.org/)

Thanks
