get groups sometimes returns empty array

[jaroslaw-weber]

im not sure why but this was happening to me today. version: 5.1.10

const max = 2;
  const groupKey1 = 'A';
  const groupKey2 = 'B';
  for (let i = 0; i < 200; i++) {
    await bullProTestQueue.add(
      `test-${groupKey1}`,
      { groupKey: groupKey1 /*, priority: 5*/ },
      { jobId: uuidv4(), group: { id: groupKey1 } },
    );
    await bullProTestQueue.add(
      `test-${groupKey2}`,
      { groupKey: groupKey2 /*, priority: 5*/ },
      { jobId: uuidv4(), group: { id: groupKey2 } },
    );
  }
  const jobs = await bullProTestQueue.getJobs();
  const getGroups = await bullProTestQueue.getGroups();
  if (getGroups.length !== 2) {
    throw new Error('Group is not created');
  }

getGroups.length was 0. flushing redis didn't work. eventually it worked but i didn't do big change to the code.

This is weird, did you face the same behavior in more updated versions?
