AWS EBで「Unhandled exception during build: invalid literal for int() with base 8: '493'」エラーの対処

概要

AWSのElastic Beanstalkで.ebextensionsを利用時にデプロイでエラー発生
（ちなみにPHPでLaravel）

/var/log/cfn-init.log

2021-01-23 02:10:56,395 [ERROR] -----------------------BUILD FAILED!------------------------
2021-01-23 02:10:56,395 [ERROR] Unhandled exception during build: invalid literal for int() with base 8: '493'

    file_is_link = "mode" in attribs and stat.S_ISLNK(int(attribs["mode"], 8))
ValueError: invalid literal for int() with base 8: '493'

今回解消した方法

.ebextensions/hogehoge.configファイルの内容を修正（modeのパラメータを"で囲む）

files:
  "/hoge/fuga.txt":
    mode: 000755

files:
  "/hoge/fuga.txt":
    mode: "000755"
