web.config doesn't have mime type for .json from nitro preset iis-node

[js-writer]

Environment

Node 18.
Nuxt 3.15.1 with Nitro 2.10.

Azure Windows, iis_node web app.

Reproduction

Create simple nuxt app and deploy it to Azure Web App on Windows IIS with Node server.

Describe the bug

Nitro create web.config when build contains preset iis-node. But web.config doesn't include json mime types so server returns error 404:

Is there a way to add mime type for iis setting in nuxt.config.ts?

Additional context

No response

In order to add additional config to the generated .output/web.config for a nuxt project:

export default defineNuxtConfig({
  nitro: {
    iis: {
      mergeConfig: true,
    },
  }
});

web.config (in project root)

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <staticContent>
      <mimeMap fileExtension=".webmanifest" mimeType="application/manifest+json" />
      <mimeMap fileExtension=".wasm" mimeType="application/wasm" />
      <mimeMap fileExtension=".json" mimeType="application/json" />
    </staticContent>
  </system.webServer>
</configuration>

Or full config to override:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<configuration>
  <system.webServer>
    <webSocket enabled="false"/>
    <handlers>
      <add name="iisnode" path="index.js" verb="*" modules="iisnode"/>
    </handlers>
    <rewrite>
      <rules>
        <rule name="NodeInspector" patternSyntax="ECMAScript" stopProcessing="true">
          <match url="^index.js/debug[/]?"/>
        </rule>
        <rule name="StaticContent">
          <action type="Rewrite" url="public{PATH_INFO}"/>
        </rule>
        <rule name="DynamicContent">
          <conditions>
            <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="True"/>
          </conditions>
          <action type="Rewrite" url="index.js"/>
        </rule>
      </rules>
    </rewrite>
    <security>
      <requestFiltering>
        <hiddenSegments>
          <remove segment="bin"/>
        </hiddenSegments>
        <requestLimits maxAllowedContentLength="4294967295"/>
      </requestFiltering>
    </security>
    <httpErrors existingResponse="PassThrough"/>
    <iisnode watchedFiles="index.js" node_env="production" debuggingEnabled="false" loggingEnabled="false"/>
    <staticContent>
      <mimeMap fileExtension=".webmanifest" mimeType="application/manifest+json"/>
      <mimeMap fileExtension=".wasm" mimeType="application/wasm"/>
      <mimeMap fileExtension=".json" mimeType="application/json"/>
    </staticContent>
  </system.webServer>
</configuration>
