This issue occurred because the document was not properly detached when the client was deactivated. This has been modified in #907 to ensure that document detachment is correctly reflected when deactivating a client.

After these modifications are applied, correction logic is required for clientInfos with deactivated status that already have attached documents.

Through the query below, you can search for documents that meet the conditions and perform modifications on each.

db.clients.find({
  status: 'deactivated',
  documents: { $ne: null },
  $expr: {
    $gt: [{
      $size: {
        $filter: {
          input: { $objectToArray: "$documents" },
          as: "doc",
          cond: { $eq: ["$$doc.v.status", "attached"] }
        }
      }
    }, 0]
  }
}).forEach(doc => {
  var updatedDocuments = {};

  for (var key in doc.documents) {
    if (doc.documents[key].status === 'attached') {
      updatedDocuments[key] = {
        status: 'detached',
        client_seq: 0,
        server_seq: 0
      };
    } else {
      updatedDocuments[key] = doc.documents[key];
    }
  }
  
  var currentTime = new Date();

  db.clients.updateOne(
    { _id: doc._id },
    { 
      $set: { 
        documents: updatedDocuments,
        updated_at: currentTime
      } 
    }
  );
});

This was fixed by #907
