I'm trying to get the pascal language server working on Visual Studio Code and
during testing I found that sending null values to the server is causing
problems. i.e.:
...
"processId": 3997,
"clientInfo": {
"name": "vscode",
"version": "1.47.3"
},
"rootPath": null,
"rootUri": null,
...
This is translated by the RPC layer to a message like:
{"jsonrpc":"2.0","error":{"code":-32603,"message":"Cannot convert data from
Null value"},"id":1}
According to the protocol null values are allowed so is there a way I can
accept null values gracefully instead of failing with an error? In particular
rootPath is trying to be mapped to a string so it could be translated to just
'' and that would be better than giving this error that prevents the server
from working entirely and causes very confusing errors that are hard to debug.
Regards,
Ryan Joseph
