Error: HTTP 404 fetching output.gff.tbi

[WSCAAA]

When I tried to use my local .gff file in shiny, I got this error. And I found that the detail about the output.gff track is

config.type FeatureTrack config.trackId GRCh38_output config.name output config.assemblyNames GRCh38 config.adapter.type Gff3TabixAdapter config.adapter.gffGzLocation output.gff config.adapter.index.location output.gff.tbi But when I tried to upload this .gff file to JBrowseR Desktop I find that when the config.adapter.type is Gff3Adapter, the track can be load. I wonder if there is a way to change config.adapter.type in shiny.
