Guy Shechter
08/19/2021, 4:09 AMI’m using the following configuration for my
sst.API Copy code
cors: {
allowCredentials: true,
allowHeaders: ['*'],
allowMethods: ['*'],
allowOrigins: ['<https://mydomain.com>', '<https://dev.mydomain.com>', '<http://localhost:3000>'],
exposeHeaders: ['Content-Range', 'Access-Control-Allow-Origin']
},a

08/19/2021, 4:11 AM@Guy Shechter did you check the console?
Adrián Mouly
08/19/2021, 4:12 AMI mean AWS console.

08/19/2021, 4:12 AMWhere in the AWS console? The cors configuration on the API GW is what I would expect

Adrián Mouly
08/19/2021, 4:19 AMIn methods.

08/19/2021, 4:20 AMJavascript accepts it, I guess typescript wants the CorsHttpMethod.ANY

Adrián Mouly
08/19/2021, 4:31 AMOh yeah, thought you were using TS.

08/19/2021, 5:32 AMwhat if you set
cors: trueg

08/19/2021, 5:38 AMAs someone previously wrote, it’s often not a CORS issue at all. In this case it was a capitalized letter in the URL. 🤦

Adrián Mouly
08/19/2021, 5:39 AMAh the problem is the HTTP ERRORS then.
Adrián Mouly
08/19/2021, 5:40 AMThe errors are not returning the cors.
Adrián Mouly
08/19/2021, 5:40 AMThen you get for example 400 error, and no cors header, then browser shows cors error, but it’s a 400.

08/19/2021, 5:40 AMThis happened to me on SLS lot of times, because errors schemas are defined in a separated configuration.
