Error when using the layer with the PyCryptodome lib

Question

I created a Lambda Layer to use the pycryptodome lib, however when calling the function it is returning an error, could you help me how can I correct this error to make the call?

Error Evidence:
 ![error_lib_pycrypto](/media/postImages/original/IMNc_i18GzQAmNlCPxeWjcSw)

"errorMessage": "Cannot load native module 'Crypto.Cipher._raw_ecb': Not found '_raw_ecb.cpython-311-x86_64-linux-gnu.so', Not found '_raw_ecb.abi3.so', Not found '_raw_ecb.so'",
  "errorType": "OSError",

Answer

Hello.

It may not work properly due to dependencies of the OS on which the layer was created.  
https://docs.aws.amazon.com/lambda/latest/dg/packaging-layers.html  
> The first step to creating a layer is to bundle all of your layer content into a .zip file archive. Because Lambda functions run on Amazon Linux, your layer content must be able to compile and build in a Linux environment. If you build packages on your local Windows or Mac machine, you’ll get output binaries for that operating system by default. These binaries may not work properly when you upload them to Lambda.

Most runtimes use Amazon Linux2, so try creating a layer on Amazon Linux2 and see if it works.
