**Apache Airflow version**:
1.10.9 although I think it would apply to 1.10.10, 1.10.8, 1.10.7, and 1.10.6
**Kubernetes version (if you are using kubernetes)** (use `kubectl version`):
**Environment**:
- **Cloud provider or hardware configuration**: aws
- **OS** (e.g. from /etc/os-release): Ubuntu 18.04.3 LTS
- **Kernel** (e.g. `uname -a`): `Linux 567ff872fc2d 3.13.0-170-generic #220-Ubuntu SMP Thu May 9 12:40:49 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux`
- **Install tools**:
- **Others**:
**What happened**:
If you have a DAG that has not been turned on before and you click on that DAG in the admin page and then in the DAG graph click on one of the tasks and then click on `Task Instance Details` you get the "Ooops" explosion error page. The error is:
```

```
**What you expected to happen**:
No error page. It should have loaded the standard task instance details page.
I believe the reason that this is happening is because there is no check to see if a dagrun exists in `DagrunIdDep`:
https://github.com/apache/airflow/blob/master/airflow/ti_deps/deps/dagrun_id_dep.py#L50
This is a bit of an edge case because there isn't really any reason someone should be checking out task instance details for a DAG that has never been run. That said we should probably avoid the error page.
<!-- What do you think went wrong? -->
**How to reproduce it**:
If you have a DAG that has not been turned on before and you click on that DAG in the admin page and then in the DAG graph click on one of the tasks and then click on `Task Instance Details` you get the "Ooops" explosion error page.

Thank you for re-opening this issue. I've checked the master version:
```

I can't login through the Web UI, though. It's asking me for username and password.
When I started the webserver, it said:

I triggered the "tutorial" DAG instead (from the UI), and it looks like it ran.
I can look at the task details. No mushroom cloud. So I would say this issue is fixed in master.

(I did read the documentation section you linked to, thank you; just after I already created an `admin` user and logged in.)
Don't laugh, but I can't figure out how to unpause the bash example operator. Instead of a sliding toggle switch, there is a checkbox.
I installed airflow by running "pip3 install --user ." in the top directory of the top of master.

Okay. I used `sqlite3` to change the setting in `airflow.db` via CLI as you suggested.
Now the UI is showing all 22 DAGs are unpaused.
```sql
update dag

You should compile JS files now, but this is a problematic process.
https://github.com/apache/airflow/blob/master/CONTRIBUTING.rst#installing-yarn-and-its-packages
Another solution: can you try to unpause the DAG with CLI and then go directly to the URL?

I have the same issue with my airflow, I am using version 1.10.12.
<img width="952" alt="image" src="https://user-images.githubusercontent.com/10818137/96565784-670c1800-12f7-11eb-8e30-f0d3ed76180d.png">
I cannot see the logs till the operation completes and even if the operation completes , i get this error. Why do we have to spend our time on tools with little or no support ? I will appreciate it, if there is a quick fix available as it appears a lot of people are facing the same problem.

I'm sorry, I can't tell. I don't seem to have a fully functional Airflow installation.
The console (CLI) keeps telling me:
```
Please make sure to build the frontend in static/ directory and restart the server
```
but I don't know how to do that.
And the example bash operator disappeared from the UI after I did the "yarn prod run".

Hello,
I just installed Airflow for the first time, following the [Quick Start](https://airflow.apache.org/docs/stable/start.html) guide.
I ran the bash example operator (still following the guide):
```
# run your first task instance
airflow run example_bash_operator runme_0 2015-01-01
```
And then, when I went to see how the run went, I got the error page with the mushroom cloud and the error.
Now, this is on Apache Airflow v1.10.11 (latest stable), which I see was released on July 10, 2020. And this pull request was merged on April 15th. And this issue is closed. But I'm running into the same broken behavior.
Here is my error page:
```
Ooops.
