You should set the environment variable TRANSFORMERS_CACHE to a writable directory.

without using cdk, set up the lambda but getting this error:

There was a problem when trying to write in your cache folder (/var/task/cache/). You should set the environment variable TRANSFORMERS_CACHE to a writable directory.

for default will be
/tmp
?

added

import os
os.environ['MPLCONFIGDIR'] = os.getcwd() + "/tmp/configs/"
os.environ['TRANSFORMERS_CACHE'] = os.getcwd() + '/tmp/cache/'

at the beggining of app.py solved
Thanks!
