Could you provide more detail on your execution environment, Nextflow version and Nextflow installation method please?

[slives-lab]

The environment is a linux HPC CentOS 7.
nextflow version 23.04.1.5866
I'm not sure if it was installed using:
conda install nf-core
or
conda install bioconda::nf-core
Here is the nextflow version from conda list
nextflow 23.04.1 bioconda

[pinin4fjords]

I can only think that perhaps something is broken in the nextflow/ java install, I doubt it's anything specific to this workflow.

You could try a fresh Nextflow install, perhaps in a fresh Conda env. It might also be worth asking about on the Nextflow Slack.

I tried to install nextflow in a new conda environment and the error is what I posted above. Is there an option to run without any amazon credentials ( --no-sign-request) ?

you can add this to a custom config file and provide it to the pipeline as you launch:

aws.client.anonymous = true
