Bad Sentry error messages

[kievu]

So I am using this plugin and my Sentry catch errors. However, they are very hard to understand. Here is an example.

I have uploaded source maps with:

yarn sentry-cli --auth-token=${TOKEN} releases --org=${ORG} --project={PROJECT} files ${GIT_HASH} upload-sourcemaps --rewrite --url-prefix=~/public/ ./public/*.js.map --validate

and yes the tag shows that the error is tagged with the correct git hash.

So my question are: Is it possible to get better error messages in Sentry? Is my --url-prefix correct? Have I missed out something?
