What are the steps to reproduce this bug?

The request is processed successfully.

What do you see instead?

An error:

Variable "$date" got invalid value "2023-10-06T15:30:39.548Z"; Expected type "DateTimeZ". Could not extract timezone from value.

Possible solution

https://github.com/webiny/webiny-js/blob/3bd39d50bc5855ea008f443e654a7975aeb79184/packages/handler-graphql/src/builtInTypes/DateTimeZScalar.ts#L5-L38

• Add support for 'Z' as a time offset
• Alternatively, the whole function may be able to be dropped since the graphql-scalars packages is being used as a validator
