Hi,
I am not bioinformatician, this might be a simple error. Please, help me solve this error, while running the workflow. The error states the following: error occurred with dataset. format bam, database CHM13_T2T_v2.0
Just to confirm: this is happening on Galaxy Europe?
and: have you submitted a bug report directly from Galaxy?
this is happening in Galaxy Africa, i am yet to submit a direct report to Galaxy

You are also welcome to share your error here if you want to. How to share your work is explained in here → How to get faster help with your question. You can paste the shared history link back in your reply, and please note the dataset number we should be looking at.
In general, most people should be using the GRCh38/hg38 human assembly for common analysis projects. Why? The CHM13_T2T_v2.0 human assembly exposes telomere and repetitive regions of the genome that some tools do not handle well. We have some discussion about that here (scroll down to the Q&A) → Reference genomes at public Galaxy servers: GRCh38/hg38 example
You can also send in the bug report and the EU team will see it. I just wanted to offer to help too. 
Thank you, I will share the bug report with the EU team
