[Feature] New Building Type Error Message

[avayedawadi]

Description

• Currently, if a new building type has been created but there are no standard cards in the building type, an error is thrown and a 404 message is shown.
• We would like there to be a more descriptive "error" message that tells how there is now standard cards yet added to the building type.

404 error but instead should just say that there are no cards in this building type yet

Acceptance Criteria

• More descriptive "error" message when there are no standard cards added to the building type yet.
• Message explicitly tells user that there are no cards added to the building type.

Other Notes

• To test, please create a new building type with no standard cards and make sure that the correct error message shows.
