**FAILED TO BOOTSTRAP** please scroll up and look for earlier error messages, there may be more than one.
./discourse-doctor may help diagnose the problem.

The site still works (thankfully!).
If I remove the [Data Explorer](https://meta.discourse.org/t/32566?silent=true) plugin then the site rebuilds correctly.
As soon as I add the [Data Explorer](https://meta.discourse.org/t/32566?silent=true) back in to `app.yml` it fails to rebuild the site.
The relevant sections of my `app.yml` look like this:
```plaintext
## Plugins go here
## see https://meta.discourse.org/t/19157 for details
hooks:
after_code:
- exec:
cd: $home/plugins
cmd:
- git clone https://github.com/discourse/docker_manager.git
- git clone https://github.com/discourse/discourse-solved.git
- git clone https://github.com/paviliondev/discourse-locations.git
- git clone https://github.com/merefield/discourse-onebox-assistant.git
- git clone https://github.com/discourse/discourse-data-explorer.git
## Any custom commands to run after building
run:
- exec: echo "Beginning of custom commands"
## If you want to set the 'From' email address
```
Any advice please?

Possibly 🤔
If I run [the query you have there](https://meta.discourse.org/t/duplicate-data-explorer-key-blocking-rebuild/162375/4), I get these results:
But to be perfectly honest, I’m way out of my depth here and don’t know if this is good or bad, nor, what to do next 😬

Identical - Thanks @merefield
Sure enough, I ran the query you shared in your other post and saw a few duplicated [data explorer](https://meta.discourse.org/t/32566?silent=true) queries.
I took the plunge and I did as you did, DELETEing the higher ID numbered ones, keeping the lower numbered ones in place.
Added the [Data Explorer](https://meta.discourse.org/t/32566?silent=true) plugin back to my app.yml and it rebuilt perfectly with no issues or errors.
Thanks again 🙇♂️
