I'm Sorry for the delay in getting back to you. I'm having problems with CI in Automatic Rebase. |

Don't worry about that check; that's failing because you merged the upstream changes instead of rebased them. I can rebase the PR later. |

unfortunately replaceAll isn't available in all engines we support. what about this?
Suggested change
| var escapedFilename = filename.replaceAll('"', '%22') | |
| var escapedFilename = filename.replace(/"/g, '%22') |
| body += chunk; | ||
| }); | ||
| req.on('end', function () { | ||
| assert(body.includes(escapedContentDispositionHeader), 'Expects encode "filename" field'); |

Suggested change
| assert(body.includes(escapedContentDispositionHeader), 'Expects encode "filename" field'); | |
| assert(body.indexOf(escapedContentDispositionHeader) >= 0, 'Expects encode "filename" field'); |
similarly, includes isn't available in everything either.
