Description

When a configurable variable is defined with the following type, it is identified as a mutable storage, and the compiler complains when we try to assign it to a record field default value.

Steps to Reproduce

Check the below code:

configurable string|string[]? fooConfig = ();

type Foo record {|
    string|string[]? foo = fooConfig;
|};

The error can be avoided when defined as a readonly varoable:

configurable readonly & (string|string[]?) fooConfig = ();

type Foo record {|
    string|string[]? foo = fooConfig;
|};
