Describe the bug

Placing a value in the new custom header middleware and attempting to save results in the following JS console error.

TypeError: Cannot read properties of undefined (reading '0')
    at app-schema.service.ts:272:36
    at Array.map (<anonymous>)
    at Ae.serializeFormList (app-schema.service.ts:270:17)
    at Ae.serializeFormValue (app-schema.service.ts:232:19)
    at app-schema.service.ts:248:26
    at Array.forEach (<anonymous>)
    at Ae.serializeFormGroup (app-schema.service.ts:245:29)
    at app-schema.service.ts:273:21
    at Array.map (<anonymous>)
    at Ae.serializeFormList (app-schema.service.ts:270:17)

Debugging seems to point to a potential issue in the how the config is parsed. The line that fails is the following and fieldSchemaNode.schema has no items

// TODO: Consider refactoring.
if (fieldSchemaNode?.schema?.items[0]?.schema?.type === ChartSchemaType.Dict) {
    return this.serializeFormGroup(listItem, schema);
}

To Reproduce

1. Goto Traefik
2. Edit Config
3. Add a config under Middleware for Custom Request Headers or Custom Response Headers
4. Click Save
5. Nothing happens

Expected Behavior

I would expect the config to be saved and a new middleware value to be available .
