Graph Viewer "Host must be specified" issue

[jfc4050]

hello, i'm having some issues with the XProf Graph Viewer. I'm on xprof 2.21.3.

here's the error:

There was an error in the requested URL /data/plugin/profile/data?run=2026_01_09_18_38_13&tag=graph_viewer&host=&graph_type=xla&module_name=jit__unstack(2120)&type=short_txt&show_metadata=false.

message: Http failure response for http://localhost:8791/data/plugin/profile/data?run=2026_01_09_18_38_13&tag=graph_viewer&host=&graph_type=xla&module_name=jit__unstack(2120)&type=short_txt&show_metadata=false: 500 INTERNAL SERVER ERROR
status: 500
statusText: INTERNAL SERVER ERROR
error: Host must be specified for tool graph_viewer in run 2026_01_09_18_38_13

but my browser has this URL, which has both ;host=ip-10-0-0-246 and &host=ip-10-0-0-246

http://localhost:8791/data/plugin/profile/graph_viewer;run=2026_01_09_18_38_13;tag=graph_viewer;host=ip-10-0-0-246;moduleName=jit__unstack%282120%29?run=2026_01_09_18_38_13&tag=op_profile&host=ip-10-0-0-246

any suggestions for things i can try?
