我正在尝试在Elastic Beanstalk上部署自定义项目，但是启动puma时，我的puma.log文件中出现以下错误。我不确定如何解决此问题。我假设它可能与我的yaml解析器一起使用，但是我不确定如何使用EB更新它。任何帮助将不胜感激。

我今天再次检查了日志以确保没有遗漏任何东西，并且在不同的日志文件中确实看到了对同一错误的另一个引用，但仍然告诉我很少。

如果您在app/shared/assets下有任何.json清单文件，请尝试将其删除。
此外，由于错误的YAML文件，可能会出现此错误。您可以通过运行此小脚本（在您的Rails根目录中）检查此内容，该脚本在所有子目录中递归查找所有* .yml文件并测试该文件。
require 'yaml'
d = Dir["./**/*.yml"]
d.each do |file|
begin
puts "checking : #{file}"
f = YAML.load_file(file)
rescue StandardError
puts "failed to read #{file}: #{$!}"
end
end
