Hi All,
I am trying to use the debug with attach option of VSCode using Go
extension. The application based on go that is running is the tendermint
blockchain network. on using the run and debug with attach option, I get
the following error "
Could not attach to pid:#### this could be caused by a kernel security
setting, try writing "0" to /proc/sys/kernel/yama/ptrace_scope"
the launch.json file configuration i use is:
> "name":"attach to process",
> "type": "go",
> "request": "attach",
> "mode": "local",
> "processId": 30834,
> "trace":"log"
The log file says:
