go vet "struct field tag not compatible with reflect.StructTag.Get" in CI

The structtag analyzer validates struct field tags. A tag missing the key:"value" quoting, or with a stray space, is flagged because reflect.StructTag.Get would silently fail to read it.

What this error means

go vet reports "struct field tag json:name not compatible with reflect.StructTag.Get: bad syntax for struct tag value".

go vet

./model.go:6:2: struct field tag `json:name` not compatible with reflect.StructTag.Get: bad syntax for struct tag value

Common causes

Missing quotes around the tag value

A tag like json:name lacks the required quotes; it must be json:"name" for the reflect parser to read it.

A stray space between key and value

A space after the colon (json: "name") breaks the conventional tag syntax the analyzer expects.

How to fix it

Use the key:"value" form

Quote each tag value and remove spaces around the colon.
Separate multiple keys with single spaces inside the backticks.
Re-run go vet ./....

model.go

Name string `json:"name" xml:"name"`

Let gofmt and vet guard tags

Run go vet in CI so malformed tags, which otherwise fail silently at runtime, are caught at build time.

How to prevent it

Always quote struct tag values: key:"value".
Run go vet ./... in CI to validate tags.
Avoid spaces inside the backtick tag literal except between keys.
