[hmz22]

Hi Dears.
I have problem when run project in iis

this my next.config.js

const path = require("path");
const nextOffline = require("next-offline");

module.exports = nextOffline({
generateInDevMode:true,
workboxOpts: {
swDest: path.join(__dirname, "public/service-worker.js")
}
});

and have web.config when run give me this error:
iisnode encountered an error when processing the request.

HRESULT: 0x2
HTTP status: 500
HTTP subStatus: 1002
HTTP reason: Internal Server Error
You are receiving this HTTP 200 response because system.webServer/iisnode/@devErrorsEnabled configuration setting is 'true'.

In addition to the log of stdout and stderr of the node.exe process, consider using debugging and ETW traces to further diagnose the problem.

The last 64k of the output generated by the node.exe process to stderr is shown below:

(node:10288) [DEP0005] DeprecationWarning: Buffer() is deprecated due to security and usability issues. Please use the Buffer.alloc(), Buffer.allocUnsafe(), or Buffer.from() methods instead.

(node:10288) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

Can anyone help me?
