## fi-0104: Unresolvable attribute argument {:#fi-0104}

Values of arguments for [official](/docs/reference/fidl/language/attributes.md)
FIDL attributes cannot be invalid per the attribute schema's expectation for
that argument:

{% include "docs/reference/fidl/language/error-catalog/label/_bad.md" %}

```fidl
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/bad/fi-0104.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
```

Ensure that the type of value being used as an attribute argument is correct:

{% include "docs/reference/fidl/language/error-catalog/label/_good.md" %}

```fidl
{% includecode gerrit_repo="fuchsia/fuchsia" gerrit_path="tools/fidl/fidlc/tests/fidl/good/fi-0104.test.fidl" exclude_regexp="\/\/ (Copyright 20|Use of|found in).*" %}
```
