Our current workflow requires us to upload a large amount of source maps or upload source maps very often. Is there a limit to how many source map bundles we can upload, or how many source maps a bundle can have?

You do not need to worry about how many source maps you are uploading, as we have no limit to the number of files or bundles that you can upload. The only thing to keep in mind is that we need your source maps to originate from production builds, otherwise we might not be able to match them with your stack traces correctly.
