pected string constant in ""json <- jsonlite::fromJSON(""metadata.cart.2022-07-05.json""

这个错误提示看起来是你在代码中使用了双引号，但是没有正确地转义它们。你可以尝试在字符串中使用单引号，或者在双引号前加上反斜线来转义它们，例如：

json <- jsonlite::fromJSON("\"metadata.cart.2022-07-05.json\"")

或者

json <- jsonlite::fromJSON('"metadata.cart.2022-07-05.json"')

这样应该就能够消除这个错误了。

e'x'pected intializer before

the 'x' is likely causing an error because it is not properly initialized. In C or C++ programming, variables need to be declared and initialized before they can be used. To fix this error, you should declare and initialize the variable 'x' before using it in your code. For example:

int x = 0; // initialize 'x' with a default value

This will ensure that 'x' has a valid value before it is used in your code.
