name.first() went wrong in Property.getCode()

[TedZen]

"java.util.NoSuchElementException: Char sequence is empty" occurs when generating code from {"":1}

some infos:
config:{
"pluginVersion": "3.4.0",
"isPropertiesVar": false,
"isCommentOff": true,
"isOrderByAlphabetical": true,
"propertyTypeStrategy": "NotNullable",
"defaultValueStrategy": "None",
"targetJsonConverterLib": "None",
"isInnerClassMode": false,
"customAnnotationImportClassString": "import kotlinx.serialization.SerialName\nimport kotlinx.serialization.Serializable\nimport kotlinx.serialization.Optional",
"customClassAnnotationFormatString": "@serializable",
"customPropertyAnnotationFormatString": "@optional\n@SerialName("%s")",
"enableMapType": false,
"enableMinimalAnnotation": false,
"parenClassTemplate": "",
"keywordPropertyValid": true,
"extensionsConfig": ""
}

log:
