I am new to snakemake, I have around 1000 samples and I tried to use config file and snakemake script to parallel run the verifyBAMID function, and there is an error and I don't know the error.

config.yaml

samples:
  120001:
    vcf: "/sample/120001.vcf.gz"
    bam: "/sample/120001/120001.recal.bam"
    bai: "/sample/120001/120001.recal.bam.bai"
 120002:
   vcf: "/sample/120002.vcf.gz"
   bam: "/sample/120002/120002recal.bam"
   bai: "/sample/120002/120002.recal.bam.bai"
120004:  
   vcf: "/sample/120004.vcf.gz"
   bam: "/sample/120004/120004.recal.bam"
   bai: "/sample/120004/120004.recal.bam.bai"

snakemake script:

     import os
     import yaml

     # Load the configuration file
     config = yaml.safe_load(open("config.yaml"))

     OUTPUT_DIR = "/output/"

     # Rule to specify the final output needed for the workflow completion
     rule all:
         input:
             expand(os.path.join(OUTPUT_DIR, "{sample}"), sample=config["samples"].keys())

     # Rule to run VerifyBamID
     rule verifyBAMID:
         input:
             bam=lambda wildcards: config["samples"][wildcards.sample]['bam'],
             bai=lambda wildcards: config["samples"][wildcards.sample]['bai'],
             vcf=lambda wildcards: config["samples"][wildcards.sample]['vcf'],
             id=lambda wildcards: config["samples"][wildcards.sample]
         output:
             directory(os.path.join(OUTPUT_DIR, "{sample}"))
         shell:
             """
             mkdir -p {output} && \  # Create the output directory if it doesn't exist
             VerifyBamID \
               --bam {input.bam} \
               --vcf {input.vcf} \
               --smID {input.id} \
               --out {output}/{wildcards.sample} \
               --best 2>/dev/null
             """

can anyone advice ? thanks.
