Request textDocument/hover failed.

[mrdulin]

This issue confused me for a month. My vscode go extension doesn't work well. For now it seems the intellisense doesn't work.

For example:

package application

import (
    "fmt"
    "serverless-functions-go/domain/models"
    "serverless-functions-go/domain/services"
    "serverless-functions-go/domain/services/adChannel/reports/adPerformance"
    "serverless-functions-go/infrastructure/config"
)

when I hover to the import statement, gopls give me below trace message:

[Trace - 3:07:51 PM] Sending notification 'textDocument/hover' in 1ms.
Params: {"textDocument":{"uri":"file:///Users/ldu020/workspace/github.com/mrdulin/golang/src/serverless-functions-go/application/adPerformanceReport.go"},"position":{"line":4,"character":23}}

[Error - 3:07:51 PM] Request textDocument/hover failed.
  Message: GetAST: unable to check package for file:///Users/ldu020/workspace/github.com/mrdulin/golang/src/serverless-functions-go/application/adPerformanceReport.go: no packages found for file:///Users/ldu020/workspace/github.com/mrdulin/golang/src/serverless-functions-go/application/adPerformanceReport.go
  Code: 0 

Another case, when I hover to a method,

func (uc *AdPerformanceReportUseCase) Get() error {
    googleAccountsForReport, err := uc.googleAccountService.FindGoogleAccountsForReport() // hover this method
    if err != nil {
        return err
    }
}

the gopls give me below trace messages:

This issue happens in src/serverless-functions-go project. Hope anyone can help me solve this issue.

I already post an issue https://github.com/golang/go/issues/32762 to official go repo. But it seems they don't think it's a gopls issue and they don't have time to take look at this. I don't know what's going on.

Any try

I try to reinstall all go tools for vscode-go extension at least ten times and reload the vscode window. The issue still there.

Here is my repo for reproducing this issue: https://github.com/mrdulin/golang

Sorry for the confusion on the other bug, I was explaining something else to another user--this is a gopls issue and the discussion should be moved back to that issue. I'm sorry I haven't been able to investigate it yet - we do have a lot of different things on our plate so sometimes issues slip through. I will write a follow-up there.

I'm also getting these errors:

@Davo36: Can you please open a separate issue on the Go issue tracker?
