Other information

these new methods weren't introduced in axios v1.0.0, right? I think we need to bump the peer dependency on axios to force the newer version... but I'm not sure

axios/package.json

Lines 47 to 50 in 8e0ecc4

	"peerDependencies": {
	"@nestjs/common": "^7.0.0 || ^8.0.0 || ^9.0.0 || ^10.0.0",
	"axios": "^1.3.1",
	"rxjs": "^6.0.0 || ^7.0.0"

I will check. I believe the version I have is 1.6.7. I can see when they introduced these features and make that the minimum peerDependency

@micalevisk Seems it was added into v0.27.0 in PR #4448
