After upgrading Redux Toolkit from 2.8.2 → 2.9.0, we’re encountering a runtime TypeError related to serializeQueryArgs.
This does not surface in type checking or during build, but it consistently appears at runtime after almost exactly 60 seconds.
Possible Cause - It looks like serializeQueryArgs is being called on an undefined endpointDefinition inside queryArgsApi.endpointDefinition.serializeQueryArgs.
This may be related to changes in RTK Query’s buildCreateApi defaults between 2.8.2 → 2.9.0.
Workaround - Downgrading back to 2.8.2 resolves the issue.
