UnhandledPromiseRejection when running `validate`

[ivdma]

Describe the bug

I can't get this project (the validate command) get to work properly.

Every attempt to (re-)install the needed parts ends up with a correct output, but surrounded by UnhandledPromiseRejection errors:

$ graphql-inspector validate './src/**/*.graphql.js' http://localhost:3000/graphql

(node:9770) UnhandledPromiseRejectionWarning: Error: Interface field InvoiceActionInterface.previewUrl expects type String! but InvoiceActionLetter.previewUrl is type String.

Interface field AttachmentInterface.documentUrl expects type Download! but TimelineItemAttachment.documentUrl is type Download.

(node:9770) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)
(node:9770) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

To Reproduce Steps to reproduce the behavior:

Followed the Continuous Integration guide (multiple times)

npm i -g @graphql-inspector/ci

# I only need validation command
npm i -g @graphql-inspector/validate-command 

# ... comparing the .JS files with a schema from a URL
npm i -g @graphql-inspector/code-loader @graphql-inspector/url-loader 

# Also an exact version of yargs is required, according to NPM
npm i -g [email protected] --save-exact

# and graphql packge is required
npm i -g graphql@^15.0.0

# Run the command
graphql-inspector validate './src/**/*.graphql.js' http://localhost:3000/graphql

Expected behavior

I expected this library to not raise any warnings/exceptions along the validation. Also expected the UI look similar to the example.

Environment:

• OS: macOS 12.1 (21C52) (but Ubuntu on Circle CI shows the same behaviour)
• @graphql-inspector/...: 3.0.2 (also tried all minor versions of above mentioned @graphql-inspector/... packages down to 2.6.0)
• graphql: 14.7.0
• NodeJS: 14.17.4

Additional context

Installing the CLI version of the package does the same.

These are all globally installed packages:

❯ npm ls -g --depth=0
