Thank you for the report @Oswaldo_Lorenzo ! Could you confirm exactly what you’re doing when you encounter this stack trace?

On the gene page given in your error report here:

I’m able to use the dataset selector on the top right to jump between gnomAD v2, v3.1.2, and v4.0 and I don’t see any errors. I tried a few variants, which all worked as well. For example, the following two variants seem to be directing me correctly in both directions:

If you can confirm that this is 1) still happening to you, and 2) what your steps to reproduce the problem are, that will help us dig in to locate the issue. Thanks again!
