aws lambda deployment and environment variables

[afarbman]

Hi,

Following the AWS lambda deployment guide found in here: https://devseed.com/titiler/deployment/aws/lambda/

when hitting any of the endpoints (e.g. /cog/info) I am getting a 404.
this is the response body:
{
"detail": "'/vsis3/landsat-pds/L8/001/002/LC80010022016230LGN00/LC80010022016230LGN00_B1.TIF' not recognized as a supported file format."
}

what am I missing?

@afarbman do you have landsat-pds in the bucket list ?

https://github.com/developmentseed/titiler/blob/master/deployment/aws/cdk/config.py#L20

To access file via s3:// URL, you need to allow the lambda to do HEAD/GET operation on the bucket. see https://github.com/developmentseed/titiler-pds/blob/master/stack/config.py#L21-L26

In case anyone else bumps into a weird 404,
there is a settings in app.py which restricts the allowed tiff extensions:
CPL_VSIL_CURL_ALLOWED_EXTENSIONS=".tif"

[vincentsarago]

yeah, sorry about this. I'll add a note in the app.py file

Hopefully all other config will be explained in #241

Sooo I have just hit this issue and I thought it was because my tiff files have a .tiff extension. (to .tif or not to .tiff?!).
Either way - it doesn't seem to work - even using my favourite test case...;
{"detail":"'/vsis3/planet-disaster-data/hurricane-harvey/SkySat_Freeport_s03_20170831T162740Z3.tif' not recognized as a supported file format."}

I'd quite like this on Lambda rather than resorting to EC2 - so any pointers appreciated.

[vincentsarago]

did you add planet-disaster-data bucket in https://github.com/developmentseed/titiler/blob/master/deployment/aws/cdk/config.py#L20 ?

Ah. Lovely - all works now. Thanks.
