Issue Summary

Jira Allows a project key pattern to be customized, this includes allowing special characters such as _, *,^, etc. However, this may break some functionality and throws a 404 errors

Steps to Reproduce

1. Configure Jira project key pattern to allow special characters.
2. Create a project with a special character such as _ or ^ in the project key
3. Create an issue in the project

Scenario 1
For a project that has a '_' in the project key:

1. Open an issue in a new tab.
2. Delete the issue
3. This shows a 404 error, despite the issue is successfully deleted

Scenario 2
For a project that has a '^' in the project key:

1. Open the project in the issue navigator
2. Try to switch the filer to anther from the 'Switch Filter" menu
3. This shows a 404 and the filter does not work.

Expected Results

If a project key pattern is allowed, it should not cause any error.

Actual Results

a 404 error is thrown which may affect some functionality such as the below:

"The value 'undefined' does not exist for the field 'project'"

A HAR file shows the following POST Request:

jql=project+%3D+%22undefined%22+AND+resolution+%3D+Unresolved+ORDER+BY+priority+DESC%2C+updated+DESC
&columnConfig=explicit&layoutKey=split-view&startIndex=0

Workaround

For Scenario 1, delete the issue from the issue navigator in the list or details view instead of opening it in a new tab.
For Scenario 2, a JQL search may be used.
