KeyError: 'RG'

[karen916]

Dear svtyper creative team：
I have a little trouble using the software and would like to ask for your help. I always encounter the prompt that the RG field is missing in the bam file. Is there any way to solve it?
(lumpy_env) [chenzhaojin@lfpara test1010]$ svtyper \

-B merge_1-10_1-30.bam \
-l my.bam.json

This still happens when I try the svtyper-sso module，(lumpy_env) [chenzhaojin@lfpara test1010]$ svtyper-sso \

--core 48 \
--batch_size 1000 \
--max_reads 1000 \
-i merged_all_results.vcf \
-B merge_1-10_1-30.bam \
> sv.gt.vcf
