When deploying Mem0 on AWS Lambda, you need to adjust the storage directory because Lambda only allows writing to the /tmp directory. By default, Mem0 tries to write to a directory in the user's home path, which isn’t writable in Lambda.

• Option 1: Using Environment variable

Set the MEM0_DIR environment variable to a writable path in /tmp.

MEM0_DIR=/tmp/.mem0

• Option 2: Modify the code

If you're not using environment variables, modify the storage path directly in your code.

Change this:

home_dir = os.path.expanduser("~")
mem0_dir = os.environ.get("MEM0_DIR") or os.path.join(home_dir, ".mem0")

To this:

mem0_dir = os.environ.get("MEM0_DIR", "/tmp/.mem0")
