CORS

[vincentsarago]

I think this happened with the new serverless release, can you confirm which version of serverless you are using ?
I may need to update https://github.com/vincentsarago/lambda-proxy which is handling the api-gateway integration.

$ sls --version
1.26.0

I am going to try and play with this again over the weekend to see if I didn't miss something.

[samsammurphy]

One idea might be to add the following line

"Access-Control-Allow-Credentials" : true // Required for cookies, authorization headers with HTTPS

to here perhaps?

I am not at all familiar with lambda proxies though, so that is a bit of a guess. Again, will try testing over the wkd.

[vincentsarago]

@samsammurphy I can't reproduce this but with sls 1.26.1 (event with Access-Control-Allow-Credentials set or not) is your endpoint still up and running ?

[samsammurphy]

I had removed it.. new endpoint up

const sentinel_tiler_url = 'https://r1jzg3qt9c.execute-api.eu-central-1.amazonaws.com/dev'

there is no CORS error, but it still is hitting something.. hopefully will find more info to help diagnose..

In the initScene() function there is a query for metadata on line 91.

Here is an example of one of my query urls:
https://r1jzg3qt9c.execute-api.eu-central-1.amazonaws.com/dev/sentinel/metadata/S2B_tile_20180303_17SMD_0?'pmim=5&pmax=95

here is part of a response from jquery .fail() when trying to $.getJSON such a query:

responseJSON: Object { errorMessage: "A defined coordinate reference system is required" }
responseText: "{\"errorMessage\": \"A defined coordinate reference system is required\"}"
setRequestHeader: function setRequestHeader()
state: function state()
status: 500
statusCode: function statusCode()
statusText: "Internal Server Error"

As you see the error message is "A defined coordinate reference system is required". I'm not sure why that error is raised. Any ideas?

@samsammurphy I am running into the same issue "A defined coordinate reference system is required". Have you been able to figure out the cause? landsat-tiler works normally though.

[vincentsarago]

are you using the simple or custom build ?
if you are using the simple you need to remove https://github.com/mapbox/sentinel-tiler/blob/master/serverless.yml#L18

[Dharnidharka]

@vincentsarago I am using the simple build. I'll make the suggested fix and get back to you. Thank you.

[Dharnidharka]

@vincentsarago Removing the line has resolved the issue. Thanks a lot.

[vincentsarago]

no problem @Dharnidharka, btw just checked your web, seems you are doing great stuff, love to see what you'll do with sentinel-tiler :-)

sorry @samsammurphy I should have realized that 21 days ago 🤦‍♂️,

Feel free to close here if it also worked for you

[Dharnidharka]

@vincentsarago Thank you. I recently started exploring satellite imagery and this tool is simply awesome. Will let you know if I manage to do something worthwhile on top of it :)

[samsammurphy]

🎉 that worked. thanks @vincentsarago !
