here message
(node:8) [FSTDEP019] FastifyDeprecation: reply.context property access is deprecated. Please use "reply.routeOptions.config" or "reply.routeOptions.schema" instead for accessing Route settings. The "reply.context" will be removed in fastify@5.

Context

fastify current version - 4.26.0

Tried disabling by these but no luck.
passing the --no-warnings flag to the node process
setting 'no-warnings' in the NODE_OPTIONS environment variable

any suggestion how to over come these deprecated messages ?

[Eomm]

Did you search for .context in your codebase?
Is there any fastify's plugin that is using it?

[suryalokhande]

Thank you Eomm,

Can see reference like : reply?.context?.schema?.description in cade base (around 7hits)
but i don't see any .context in register function.

It is possible to provide a
Minimum Reproducible Example?

Maybe that would help

We are on GitHub and not on stackoverflow. Provide a link to a github repo with the mvce so that each maintainer doesnt need to rebuild your example.
