Why do var scripts run when refreshing introspection?

[jinwood]

Hey,

I have some simple GQL queries setup in Bruno and have used vars / scripting to automate passing around values between requests.

When I try to refresh the schema with introspection I get errors relating to this vars. For example:

Error occurred while loading GraphQL Schema: Error invoking remote method 'fetch-gql-schema': TypeError: Cannot read properties of undefined (reading 'quoteId')

Why is this happening? Thanks
