Upgraded to v3 and now responses have changed from JSON objects to JSON strings?

[brockdub]

Hi everyone,

I just upgraded to OAS Tools v3 and immediately noticed that our responses are incorrect.
We are expecting JSON objects but now we are getting escaped strings.

For example, a response in OAS Tools v2 looked like (including headers):

{"name":"@brockdub/push-notification","version":"0.0.0"}

Content-Security-Policy: default-src 'none';base-uri 'self';block-all-mixed-content;font-src 'self' https: data:;frame-ancestors 'none';img-src 'self' data:;object-src 'none';script-src 'self';script-src-attr 'none';style-src 'self' https: 'unsafe-inline';upgrade-insecure-requests
X-Content-Type-Options: nosniff
X-Frame-Options: SAMEORIGIN
Content-Type: application/json; charset=utf-8
Content-Length: 59
Date: Tue, 30 May 2023 15:42:45 GMT
Connection: keep-alive
Keep-Alive: timeout=5

And now in OAS Tools v3:

"{\"name\":\"@brockdub/push-notification\",\"version\":\"0.0.0\"}"

Content-Security-Policy: default-src 'none';base-uri 'self';block-all-mixed-content;font-src 'self' https: data:;frame-ancestors 'none';img-src 'self' data:;object-src 'none';script-src 'self';script-src-attr 'none';style-src 'self' https: 'unsafe-inline';upgrade-insecure-requests
X-Content-Type-Options: nosniff
X-Frame-Options: SAMEORIGIN
Content-Type: application/json; charset=utf-8
Content-Length: 69
Date: Tue, 30 May 2023 15:52:45 GMT
Connection: keep-alive
Keep-Alive: timeout=5

These were the options I was using in v2:

const options = {
checkControllers: false,
strict: true,
validator: true,
router: false,
customLogger: logger,
docs: {
apiDocs: "/docs",
apiDocsPrefix: apiRootPath,
swaggerUi: "/api-docs",
swaggerUiPrefix: ""
}
};

And these are the options I'm using in v3, which has the file path addition and package.json addition:

const options = {
oasFile: oasFilePath,
packageJSON: path.resolve(__dirname, "../package.json"),
middleware: {
router: { disable: true }
},
checkControllers: false,
strict: true,
validator: true,
router: false,
customLogger: logger,
docs: {
apiDocs: "/docs",
apiDocsPrefix: apiRootPath,
swaggerUi: "/api-docs",
swaggerUiPrefix: ""
}
};

Nothing else has changed, haven't touched the specs or schemas, so I'm not sure if I'm missing something that's possibly so simple I'm not seeing it?

Any help and/or guidance is much appreciated.

Thank you all so much.
