check dlv-dap requires 1.15+

[hyangah]

In https://stackoverflow.com/questions/68753251/couldnt-start-dlv-dap, #1686 (comment) and #1716, users report dlv-dap mode does not work with go versions earlier than 1.15.
Delve DAP is slightly newer than Delve 1.7.0, and Delve 1.7.0 dropped the official support on go1.14, but strictly speaking, go1.17 is not officially out when vscode 0.27.0 was released, so not supporting 1.14 was sudden. We need to understand what's not working with 1.14 and also document the version compatibility.

We can use dlv with --check-go-version off.

I can't find where to use this options. Can you tell me? Thanks.

@luojiego Try adding the following to your launch.json configuration:

"dlvFlags": ["--check-go-version=false"],

Thanks for your reply, it seems doesnt' work.

It looks like you are adding this setting to settings.json, not launch.json. Click "Open launch.json" in the error message to get access to individual configuration that you can select from Run And Debug drop-down.
