--igenomes_base could not validate file format

Description of the bug

Hello,

When I run my job, I get the following error message: * --igenomes_base (s3://ngi-igenomes/igenomes/): could not validate file format of 's3://ngi-igenomes/igenomes/': Missing plugin 'nf-amazon' required to read file: s3://ngi-igenomes/igenomes/.
It seems this is a known issue: https://github.com/nextflow-io/nf-schema/issues/204. But in practical terms, how can I work around the problem? My skills are fairly limited beyond the basic pipeline settings. Do you have any idea how long it might take to resolve this issue ?

Thank you

Start with subworkflows/nf-core/utils_nfschema_plugin/main.nf at line 68 and the .nextflow.log referenced in the report. Reproduce the --igenomes_base validation failure with the supplied command and inspect how the pipeline handles the missing plugin or unreachable S3 path. Done means the reported input is validated successfully or the issue documents a confirmed workaround.
