Describe the bug

When I was trying to set empty or null value for authType, it returns me error of 'Cannot convert undefined or null to object' and the error seems causing by serializeConfig function. This issue seems working fine with @nuxtjs/[email protected] but not for the release after this.

Expected behaviour

I should be able to set empty/null value for authType.

I have faced this issue and identified the root cause, it's caused by the condition checking for handling object/array.

In the code below, it did not consider the fact that typeof null === 'object'
