I've followed this tutorial from the serverless website to try deploy my first AWS lambda function with a package dependency.
The error I get is STDERR: ERROR: Invalid requirement: '��' (from line 1 of /var/task/requirements.txt) I haven't been able to find a solution on using google. Having tried to go through the tutorial various times the same error keeps reoccurring, sometimes as ERROR: Invalid requirement: '\x00' or ERROR: Invalid requirement: '\x00\x01' or something similar. It seems to me that the serverless-python-requirements plugin is formatting it's own requirement file incorrectly, but I just don't know.
My requirements.txtwhen I have no dependencies is empty, which then translates to a serverless generated .serverless\requirements.txt:
��
When my requirements.txt is
numpy==1.19.2
this translates to a .serverless/requirements.txt as follows:
��n u m p y = = 1 . 1 9 . 2
I have gone through each step of the tutorial, and have not run into any problems until I run serverless deploy. This is the stack trace I get:
