You need to set the content-type to text/html in the headers of your response object, as typically it is (implicitly) set to application/json .
Projected to your case, you need to return your function in your AWS Lambda handler like:
callback(null, {
statusCode: 200,
headers: {"content-type": "text/html"},
body: "<html><body>OK</body></html>"
})
That will set the content type correctly for the client to parse.

For those that are using the serverless framework, you can configure the content-type of your function's response in your serverless.yml file, for example:
downloadImage:
handler: lib/client-app-services.downloadImage
events:
- http:
path: client/images/{filename}
method: get
cors: true
integration: lambda
response:
headers:
Content-Type: "'image/jpeg'"
Cache-Control: "'max-age=120'"
