Unable to upload files with URL encoded characters

[dburnsii]

When trying to upload a build artifact containing a + character, I get a message that looks like the following:

  Failed to publish artifacts: Failed to publish artifact dist/package-1.2.3+git1234abc.noarch.rpm: 403 Forbidden
<?xml version='1.0' encoding='UTF-8'?><Error><Code>SignatureDoesNotMatch</Code><Message>The request signature we calculated does not match the signature you provided. Check your Google secret key and signing method.</Message><StringToSign>POST

application/x-rpm
1621957503
x-goog-resumable:start
/teamcity-artifacts/dist/package-1.2.3%20git1234abc.noarch.rpm</StringToSign></Error>

This seems like a mismatch somewhere between the signature the file is assigned vs the signature used to upload. If I remove the + from the filename the upload seems to work just fine.
