rasterio error when deploying to AWS lambda with zappa

[angelosnm]

I'm trying to deploy terracotta to AWS lambda following all the relevant instructions with the vritualenv etc (A serverless Terracotta deployment on AWS Lambda) using RDS as well and the below error comes up on "zappa deploy"

concurrent.futures.process._RemoteTraceback:

During handling of the above exception, another exception occurred:

The above exception was the direct cause of the following exception:

Huh, haven't seen that one before. Can you give us a bit more information about your setup? What OS, how did you install rasterio / GDAL?

[angelosnm]

I haven't install GDAL. I just run the "pip install" commands without any issues (Ubuntu 20.04)

[dionhaefner]

Could you try running this command and see if you get the same error?

$ python -c "from rasterio.crs import CRS; print(CRS.from_user_input('epsg:3857'))"

[angelosnm]

Thanks for your comment!

Yes, the same error appears when running this command

[dionhaefner]

Okay. So your installation is broken, but I'm not exactly sure how it's broken. I suggest you re-install everything, and if that doesn't work, open an issue at rasterio.
