Description

1.3.5
What platform is your computer?
Darwin 24.5.0 arm64 arm
What steps can reproduce the bug?
Repo: https://github.com/60pfennig/elysia-standalone-schema-bug
Creating a guard with schema: "standalone" with an optional property (eg: t.Object({token: t.Optional(t.String))}).
Create a post handler after it with own schema.
What is the expected behavior?
The guard passes and the next handler gets called with its own validated schema
What do you see instead?
Following run time error occurs:
1059 | ...schema,
1060 | properties: {
1061 | ...newSchema.properties,
1062 | ...schema.properties
1063 | },
1064 | required: [...(newSchema?.required ?? []), ...schema.required]
^
