Context

This was detected in a workspace configured with GoLand and with GoLand locally installed, as well as JetBrains Gateway (as referred to JetBrains IDEs documentation page), but without JetBrains Toolbox installed.

Description

When attempting to open GoLand through the button on the workspace, users receive the error message "GoLand must be installed first" even if GoLand is already installed. Based on discussions in #jetbrains channel, it was mentioned that to use GoLand, it is required to have JetBrains Toolbox installed.

Suggested Fix

Change the error message to something more informative, e.g.: "To use GoLand, you need to have JetBrains Toolbox installed." Additionally, update the documentation to reflect this requirement. We should also check if the same issue occurs for workspaces configured with IntelliJ, and ensure the error message applies across different JetBrains IDEs.

Additional note: this appears to be a small change in
