Kibana error opening transforms page


I've been working on transforms today without much of an issue. I went to create another transform in the Kibana UI but as soon as I click "create transform" the page loads with the following error:

> Error: Failed to execute 'removeChild' on 'Node': The node to be removed is not a child of this node.

Can you please share which Kibana version you are running?
Does this mean you cannot even get to the part where you select a Kibana index pattern before the full wizard to create the configuration loads? If yes, can you please try if you still can create a new visualization for a dashboard? Depending on the version you are on this will have the same index pattern selection screen so we can verify if it's something specific about the transforms UI or a more general problem.


This is elastic 8.

To provide more context: I am testing a transform on a sample set of data. I took 4 sample documents from an index and reindexed them into a different index.

First was to copy sample documents from one index to the next. The new index has backing index template that matches old index:

POST _reindex
  "source": {
    "index": "test_index_1",
    "query": {
      "term": {
        "_id": "yz7pCX8YvCeAxVD6hXTd"
  "dest": {
    "index": "test_index_2"

After this I created my data view. I can verify the data is in discover. I then go to transforms. I click create transform. I choose the data view for test_index_2 and then it goes to the error message.

As a test I chose a different transform and that didn't give me any error message.

Unfortunately I wasn't able to reproduce your problem so far. Can you share the exact version you are on? Is that 8.0.0 or something later?

One thing worth checking might be if you have any browser extensions running that might interfere with the page. Try disabling them or temporarily use a browser you don't regularly use without extensions.

If possible, it would be great if you could share the details of the failing index (mapping + docs).
