Unable to find data source with id {0}

Error message

Unable to find data source with id {0}

What it means

Thrown when DBUtils.findDataSource() cannot locate a datasource by its ID within the specified project. The datasource ID was present in the configuration (so [148]'s null check passed) but the datasource was not found in the project's connection registry. The message includes the actual datasourceId for diagnosis.

Solutions

1. Open the debug configuration and re-select the correct datasource
2. If the datasource was deleted, recreate it with the same connection details then update the debug configuration
3. Verify the project name stored in the launch configuration (ATTR_PROJECT_NAME) matches the project where the datasource lives

// Verify the datasource exists before launching
String datasourceId = configuration.getAttribute(
    DBGConstants.ATTR_DATASOURCE_ID, (String) null);
String projectName = configuration.getAttribute(
    DBGConstants.ATTR_PROJECT_NAME, (String) null);
if (DBUtils.findDataSource(projectName, datasourceId) == null) {
    // datasource no longer exists — inform user to re-select
}

try {
    DebugUtils.getDataSourceContainer(configuration);
} catch (CoreException e) {
    String msg = e.getStatus().getMessage();
    if (msg.startsWith("Unable to find data source")) {
        // datasource deleted — prompt user to rebind the configuration
    }
}

When it happens

Trigger: Calling DebugUtils.getDataSourceContainer() where datasourceId is non-null but DBUtils.findDataSource(projectName, datasourceId) returns null. The lookup searches the named project's datasource registry.

Common situations: The datasource was deleted after the debug configuration was created. The datasource was moved to a different project. The project name changed so the lookup targets the wrong project. The datasource ID reference is stale.
