In Laravel 6, Lighthouse, debugMessage”: “Expected a value of type \”string\” but received:[\”en-US\”,\”zh-CN\”,\”sp-ES\”,\”fr-FR\”,\”de-DE\”,\”pt-PT\”,\”it-IT\”]
1. In Laravel 6, Lighthouse, debugMessage”: “expected a value of type \”string\” but received:[\”en-US\”,\”zh-CN\”,\”sp-ES\”,\”fr-FR\”,\”de-DE\”,\”pt-PT\”,\”it-IT\”]. as shown in Figure 1
![在 Laravel 6、Lighthouse 中，debugMessage": "Expected a value of type \"String\" but received: [\"en-US\",\"zh-CN\",\"sp-ES\",\"fr-FR\",\"de-DE\",\"pt-PT\",\"it-IT\"]](https://www.shuijingwanwq.com/wp-content/uploads/2022/05/1-1.png)

2. Print dd($resolveddata[‘current’][‘settings’][31]); , the result is as follows. The value of the 31st element is in the array format. as shown in Figure 2
![打印 dd($resolvedData['current']['settings'][31]); ，结果如下。第 31 个元素的 value ，为数组格式](https://www.shuijingwanwq.com/wp-content/uploads/2022/05/2-18.png)
Figure 2
Illuminate\Support\Collection {#11225
#items: array:33 [
"available_languages" => array:4 [
"id" => Modules\ThemeStore\Resolver\Id {#11223
#prefixes: array:3 [
0 => "theme"
1 => "current"
2 => "available_languages"
]
}
"settingId" => "available_languages"
"value" => array:7 [
0 => "en-US"

5 => "pt-PT"
6 => "it-IT"
]
"type" => "select"
]
]
}
3. Edit the parser method, var_dump($value);, print out a list of values
int(0)
int(0)
string(7) "#ff0000"
string(7) "#000000"
string(7) "#990000"
string(7) "#212529"
string(7) "#999999"
string(7) "#c90d0d"
string(40) "linear-gradient(90deg, #c90d0d, #c90d0d)"
string(7) "#c90d0d"
string(40) "linear-gradient(90deg, #c90d0d, #c90d0d)"
string(7) "#ffffff"
string(40) "linear-gradient(90deg, #ffffff, #ffffff)"

[4]=>
string(5) "de-DE"

string(5) "pt-PT"

string(5) "it-IT"
}
string(6) "global"
4. Since the type of value is set to: String, you need to convert the array to String format. Otherwise, the response format will fail.
'value' => is_array($value) ? json_encode($value) : $value,
5. “DebugMessage”: “expected a value of type \”string\” but received:[\”en-US\”,\”zh-CN\”,\”sp-ES\”,\”fr-FR\”,\”de-DE\”,\”pt-PT\”,\”it-IT\”]”, has disappeared. As expected. Only “debugmessage” is left: “Cannot return null for non-nullable field \”Themepreset.Sections\”.”. As shown in Figure 3
!["debugMessage": "Expected a value of type \"String\" but received: [\"en-US\",\"zh-CN\",\"sp-ES\",\"fr-FR\",\"de-DE\",\"pt-PT\",\"it-IT\"]", 已经消失。符合预期。仅剩下 "debugMessage": "Cannot return null for non-nullable field \"ThemePreset.sections\"."](https://www.shuijingwanwq.com/wp-content/uploads/2022/05/3-1.png)

#items: array:3 [
"header" => null
"footer" => null
"announcement-bar" => null
]
}
7. Finally, find the reason, because the callback function in the collection is not return . as shown in Figure 4
Figure 4
private function resolveSectionSettings(ThemeSettingSet $preset, Theme $themeSettingSchema, Id $id)
{
$themeId = $this->viewStorage->getThemeId();
return collect($preset->getSections())
->map(function(SectionSetting $sectionSetting, $sectionId) use($themeSettingSchema, $id, $themeId) {
$sectionSchema = $themeSettingSchema->getSection($sectionId);
$globalSectionId = $id->with($sectionId);
return $this->resolveSectionSetting($globalSectionId, $sectionId, $themeId, $sectionSetting, $sectionSchema);
});
}
8. Request response 200. as shown in Figure 5
