Blank page after copying empty values in Format Prompt Values #5133
Description
Describe the bug
When opening the Format Prompt Values dialog and leaving the input field empty, clicking on Copy to clipboard throws a console error, leaves the page completely blank, and any unsaved flow is lost.
To Reproduce
Go to the Format Prompt Values section.
Leave the first field (input) empty ("").
Click the Copy to clipboard icon.
The page turns blank and the following error appears in the console:
index-C6GKaUTA.js:62 TypeError: Cannot read properties of undefined (reading 'writeText') at V (CredentialListDialog-BNh2u_Ji.js:6:1433) at enableClipboard (CredentialListDialog-BNh2u_Ji.js:6:2124) at t.<anonymous> (main-zDAGC98s.js:13:18279)
Expected behavior
It should either:
Copy an empty string ("") to the clipboard, or
Gracefully handle the undefined value without throwing an error or refreshing the page.
