Hi! It looks like you may have a corrupted object here, and I apologize that this is not logging any error message. The 304 status code is normal, it indicates that these files are already cached by the browser and don't need to be re-downloaded. A few questions: - Did you import this visualization from a previous version of Kibana? - Was this visualization working recently? - Could you paste the results of running this command in the Dev Tools Console? the `` can be grabbed from the URL bar. It's the alphanumeric sequence after `/edit/` and before the `?`. It's of the form 93d...df2: ```auto GET /.kibana/_doc/visualization: ``` ---

@majagrubic This looks similar to other cases you've encountered. How could we confirm this is the same issue and/or fix the visualization? ---

This problem could be related to a missing index-pattern. Unfortunately, we don't handle the error here very well and just swallow the exception, so there's not a lot of information into what's going around. Could you please fetch all your index patterns and cross-reference them with the index patterns in the `references` part of your exported visualization? Basically, you're looking for just one index pattern: `af123ca0-82de-11ea-a587-0fefe6ee9b2d` You can get all your index patterns by querying `.kibana` index from the dev console: > GET /.kibana/\_search?q=type:"index-pattern" > { > "\_source": false > } ---

In the list of the index patterns, you have two index patterns: `apm_static_index_pattern_id` and `9c49f420-90c9-11ea-be48-1f045d3a2df2`. Your visualization references the index pattern with the id: `af123ca0-82de-11ea-a587-0fefe6ee9b2d`, which is not present in your index patterns. I suspect you deleted that index pattern in the meantime. Unfortunately, in visualization references we only store index pattern ids, so I can't tell you what that index pattern was called. The mitigation here is that in the saved objects UI you modify your visualization by deleting the content of the `filter` array from `searchSourceJSON. You can do that as follows: 1. go to the management console 2. select `Saved Objects` from the menu 3. find your visualization in the list 4. from the actions selector, select `Inspect` ![Screenshot 2020-05-27 at 10.32.38](https://us1.discourse-cdn.com/elastic/original/3X/a/5/a59a92f079509c9a5d8a984bdcec311b152dac6e.png) 5.Find `kibanaSavedObjectMeta.searchSourceJSON` 6. Delete all the content of the `filter` array, but leave `filter` keyword and an empty array ![Screenshot 2020-05-27 at 10.34.52](https://us1.discourse-cdn.com/elastic/original/3X/c/b/cbf3c45e3fbd481a0da0d76deb3c862b690cd689.png) 7. Save This will allow the visualization to load but without filters. You will need to recreate your filters. In the meantime, I'm investigating with my colleagues if there was a migration gone wrong that caused this index pattern to be deleted and if we can prevent this from happening in the future. ---

> [@majagrubic](#): > > In the meantime, I'm investigating with my colleagues if there was a migration gone wrong that caused this index pattern to be deleted and if we can prevent this from happening in the future. @majagrubic Thank you for your help. I removed the content in the filter according to your method, but when I open the page again, it still shows that it is empty, which is a bit strange. And I noticed that the id of this index pattern is also different from the one in the picture above. Does this matter? ![image](https://us1.discourse-cdn.com/elastic/original/3X/9/d/9db3d6acee60bfb07c9f5c0c4d48d771d3fa2407.png) ![image](https://us1.discourse-cdn.com/elastic/original/3X/b/7/b7e7d1375889b4029beabe48ea6356b0757febbb.png) You are right, I did delete an index pattern before. Before this, I also have a question, can the visualize objects already designed change its source index? ---

On a second glance, I see that both your visualization AND your filter reference a missing index pattern. I don't think there's anything you can do here, except recreating a deleted index pattern. > And I noticed that the id of this index pattern is also different from the one in the picture above I am not sure I understand what you mean here. It's the same missing index pattern id in both places. > can the visualize objects already designed change its source index? It is only possible by modifying the index pattern id in the saved objects inspector directly, in a similar way you modified the filter array. I'm afraid we don't have a UI-friendly way of doing this. We have an open issue for this, so you can track progress there: [Ability to change the index pattern on a visualization · Issue #17542 · elastic/kibana · GitHub](https://github.com/elastic/kibana/issues/17542) ---

@majagrubic Thanks for your help, now I think the fastest solution is to delete visualization directly and redesign one ---

@majagrubic **Every Visualization has an index-pattern, but if the index-pattern is lost, all Visualization can't be used, which is very bad. (And it cannot be fixed, for example, change to the new index-pattern id)** _#In another case, two elastic clusters have the same data but different index-pattern names. If I want to import the'Visualization Objects' of cluster A into cluster B, an error will occur. That's troublesome when migrating data(I remember encountering this kind of error in version 5.X)_ ---

Hm, I'm not sure how it would work if the visualization would just switch to a new index pattern. The data in the visualization is tied to your index pattern. ---
