Lerna (powered by Nx) Cannot read properties of undefined (reading 'projects')

[lyj1994]

Current Behavior

I use lerna@8.1.3 nx@19.4.3.

TypeError: Cannot read properties of undefined (reading 'projects')

I noticed that in the normalizeTargetDependencyWithStringProjects function, if projects='dependencies', it will directly return.
https://github.com/nrwl/nx/blob/master/packages/nx/src/tasks-runner/utils.ts#L198

export function normalizeTargetDependencyWithStringProjects(
  dependencyConfig: TargetDependencyConfig
): Omit<TargetDependencyConfig, 'projects'> & { projects: string[] } {
  if (typeof dependencyConfig.projects === 'string') {
    /** LERNA SUPPORT START - Remove in v20 */
    // Lerna uses `dependencies` in `prepNxOptions`, so we need to maintain
    // support for it until lerna can be updated to use the syntax.
    //
    // This should have been removed in v17, but the updates to lerna had not
    // been made yet.
    //
    // TODO(@agentender): Remove this part in v20
    if (dependencyConfig.projects === 'self') {
      delete dependencyConfig.projects;
    } else if (dependencyConfig.projects === 'dependencies') {
      dependencyConfig.dependencies = true;
      delete dependencyConfig.projects;
      return;
      /** LERNA SUPPORT END - Remove in v20 */
    } else {
      dependencyConfig.projects = [dependencyConfig.projects];
    }
  }
  return dependencyConfig as Omit<TargetDependencyConfig, 'projects'> & {
    projects: string[];
  };
}

This leads to a TypeError: Cannot read properties of undefined (reading 'projects') being thrown at the call site.
https://github.com/nrwl/nx/blob/master/packages/nx/src/tasks-runner/utils.ts#L72

const noStringConfig =
    normalizeTargetDependencyWithStringProjects(dependencyConfig);

  if (noStringConfig.projects) {
    dependencyConfig.projects = findMatchingProjects(
      noStringConfig.projects,
      graph.nodes
    );
  } else if (!noStringConfig.dependencies) {
    dependencyConfig.projects = [currentProject];
  }

Expected Behavior

Don't throw type error.

I have the same issue without being on a Lerna Project.
I upgraded my workspace to nx 19.5.0 and when I run the command
nx run-many --target=build

I have the same error:

 Cannot read properties of undefined (reading 'projects')
