Wildcard for Sourcemap ignores file:// protocol but no folders

We figured out that our sourcemaps weren’t being applied for file://android_assets/etc unless we appended the “android_assets” to the beginning of our sourcemap files (i.e. ~/android_assets/etc). This works for fixing our issue with Android, but means we’ll have to re-upload the sourcemap files a 2nd time for iOS. Was wondering if there was a way to fix this.

This is a limitation of the prefix right now. The ~ prefix literally omits protocol/host/port ONLY, which is why file:// works.

One workaround is to use data callbacks to modify the data before transport.

How do you do this? Any examples? Where is there any documentation on “data callbacks”?
