Bedtools not found while testing master branch

I was running the pipeline locally using the master branch and got an error message "tests/test_integration_workflow/test.local.sh: line 59: bedtools: command not found"

These are the steps:

git clone ssh://git@git.scicore.unibas.ch:2222/zavolan_group/pipelines/rhea.git
cd rhea/
conda activate rnaseq_pipeline
ml Singularity/2.6.1
nohup bash tests/test_integration_workflow/test.local.sh > integration_workflow_local.log

This is the execution log: integration_workflow_local.log
