strictDynamic Timeout Issue on Vercel Deployment

[raveena-hztl]

I’m facing an issue with implementing a Content Security Policy (CSP) using the @next-safe/middleware library with strictDynamic function in Next.js / Sitecore XM Cloud JSS with Next.js application hosted on Vercel.

with this function : strictDynamic({ fallbackScriptSrc: directives['script-src'] }))
Error: Your function was stopped as it did not return an initial response within 25s

"@next-safe/middleware": "^0.10.0",
"next": "^14.1.0",

I’d appreciate any insights or suggestions from the community on:

• Possible reasons for this timeout error on Vercel.
• Workarounds or configurations that might resolve the issue.
• Similar experiences with strictDynamic or other middleware-related functions on Vercel.

Thank you in advance for your help!
