Lambda error: no module found. Cryptography.hamtaz.bindings._constant_time

I created a lambda function which upload data to snowflake. I installed a all requirements in folder and zipped along with my main python file. While running in AWS it shows an error:

no module found. Cryptography.hamtaz.bindings._constant_time.

But I have this module at specified path. I don't know why it shows an error. I don't know why the error is arise.

Here is the code:

main(event, context):
  import snowflake.connector
  cnx = snowflake.connector.connect( user='xxx', password='yyyyy', account='zzzz', database="db Name", schema = "schema Name" )
  try:
    query = "SELECT * FROM Table_Name"
    cnx.cursor().execute(query)
  finally:
    cnx.close()

I faced same issue recently and found it is a problem with windows environment, try to create linux environment, install Python, packages, zip your code with all libraries and then throw back to AWS lambda, hopefully it will work.

No module named 'cryptography.hazmat.bindings._constant_time , If you're filing a bug (as opposed to a feature request), please try the No module named 'cryptography.hazmat.bindings. To use it on lambda you must use linux binaries, while on your local machine you'll be using windows versions. people doing this so you should be able to find resources online. The version of cffi that comes with pypy 2.6.1 is versioned as 1.3.0, so something has overwritten it. cffi is not a traditional python module in pypy, so upgrading (or downgrading) it will break it. I'm unsure how to resolve that short of reinstalling pypy actually (you can't just use pip to install the right version in this case).


i needed to set up a virtualenv for my lambda package to work. i also found pip install snowflake-connector-python did not install some cryptography libraries, although if i navigated to the directory i wanted them to be put in, adding --target . did cause those libraries to get installed.

For python 3.6, when I encountered the error "Unable to import module 'main': No module named '_cffi_backend'" in an AWS Lambda Function, I was able to run mv _cffi_backend.cpython-36m-x86_64-linux-gnu.so _cffi_backend.so in my linux docker image with virtualenv and the issue was resolved. Like mentioned above, some dependencies might be better placed with --target, to get them where you need them
