Invalid escape character in c_cpp_properties.json

[brunojoyal]

VSCode is suddenly unhappy with c_cpp_properties.json. My platformio.ini file contains the build flag

-DTEMPLATE_PLACEHOLDER="\'\~\'"

which yields to the following in c_cpp_properties.json:

with the message "Invalid escape character in string. jsonc(261)"

Everything compiles just fine but I have to manually fix c_cpp_properties.json in order for Intellisense to work properly. I did not have this problem before but I'm not sure what caused it. Any help appreciated!

Same since upgrade to version 1.73.1. If i remove the escape chars, Intellisense, it works again. Nevertheless, vscode automatically set them back and so at each vscode restart i have to repeat the operation.

What is your platformio.ini?

[ivankravets]

What should be the real value of TEMPLATE_PLACEHOLDER?

I'm having this same issue with a different build flag. What is adding these extra slashes? It is driving me nuts!
