defaultValue false and null not shown in doc-viewer

[Migushthe2nd]

Describe the bug
The schema can include default values for query arguments. The doc-viewer shows this value next to the query argument name. In the case of false and null this does not happen. In the introspection query, default values are always sent as a string:

• not set ->"defaultValue": null
• null -> "defaultValue": "null"
• false -> "defaultValue": "false"

I think this is the current code that is used to parse the incoming value:

altair/packages/altair-app/src/app/modules/altair/services/gql/oldBuildClientSchema.ts

Lines 334 to 336 in 18ab729

	const defaultValue = inputValueIntrospection.defaultValue
	? valueFromAST(parseValue(inputValueIntrospection.defaultValue), type)
	: undefined;

To Reproduce
Steps to reproduce the behavior:

1. Set the default value of a graphql query argument in the schema to null or false
2. Connect to the API
3. See no indication that the default value is null or false

Expected behavior
The doc-viewer shows the default value as null or false

Thanks for reporting this! I'd look into it as soon as I can. Note if you identify the issue, you can always create a PR. That way it can be resolved faster, otherwise I'll try to take a look when I can

Seems to be fixed in the arguments list

However, not yet in the fields list
