Bitrise, proguard & sentry

I have an android app that I bundle using bitrise, and with bitrise I also sign my app. When an exception occurs the exception is obfucated and doesn’t get de-bfuscated on sentry. When I generate the apk locally, using proguard, everything seems to work correctly, as I can see that the proguard mapping file is uploaded automatically in sentry and if an exception occurs, it can be de-obfuscated; this is not true when I generate the apk in bitrise:

I have a sentry.properties file in my project directory configured like that:

defaults.url=https://sentry.io/
defaults.org=“organization”
defaults.project=“project-name”
auth.token=“token”

and I have configured the plugin:

sentry {

// Enables or disables the automatic upload of mapping files
// during a build.  If you disable this, you'll need to manually
// upload the mapping files with sentry-cli when you do a release.
autoUpload true

// Disables or enables the automatic configuration of Native Symbols
// for Sentry. This executes sentry-cli automatically so
// you don't need to do it manually.
// Default is disabled.
uploadNativeSymbols false

// Does or doesn't include the source code of native code for Sentry.
// This executes sentry-cli with the --include-sources param. automatically so
// you don't need to do it manually.
// Default is disabled.
includeNativeSources false

}

Any suggestion about what I might be missing?
