tgsearch/tgrep should have proper error handling [was #21588]
Trying to lookup an non existing object on the textgridrep website triggers an ugly error.
https://textgridrep.org/browse/-/browse/12_4 states
"TextGrid Browse is temporarily unavailable."
It should state that this object can not be found instead. But the underlying tgsearch operantion: https://textgridlab.org/1.0/tgsearch-public/info/textgrid:1234/metadata also just throws an error. Proper error handling needs to be put into place here.
