Suddenly from today, the response of productVariants (GraphQL Admin API) has changed.

[cuervo]

Hi.

0 hits in `productVariants` query.
Of course, the product existed and I was able to get it until yesterday.
Does not hit if vendor contains half-width space.

Does not hit if vendor contains half-width space

 But `products` query is fine.

Hit even if half-width space is included

Is this a bug in the GraphQL Admin API?
If it's not a bug, is there a good solution?

Thank you.
