arrayInputCoercion not working

^{Originally posted by **markedwards** August 5, 2022}
I have the following codegen.yml:
```
overwrite: true
schema: "lib/api/schema.graphql"
documents: "lib/api/(fragments|mutations|queries)/**/*.ts?(x)"
generates:
lib/api/types.ts:
config:
avoidOptionals:
field: true
namingConvention:
enumValues: keep
nonOptionalTypename: true
plugins:
- "typescript"
- "typescript-operations"
```
I'm not seeing arrayInputCoercion applied. In other words, array properties of input types are generated as only an array, rather than either an array or a single value of the given type.

Does this only work on variables, and not on input types?
