arango.exceptions.GraphTraverseError: [HTTP 404][ERR 404] unknown path '/_api/traversal' when using traverse (arangodb 3.12) #333
Description
(running python 3.10) We recently upgraded to arangodb 3.12 and now calling traverse() yields the following error:
Traceback (most recent call last):
File "/app/test.py", line 47, in <module>
result = graph.traverse(
File "/root/.cache/pypoetry/virtualenvs/yeti-9TtSrW0h-py3.10/lib/python3.10/site-packages/arango/graph.py", line 486, in traverse

Looks like the endpoint was deprecated: https://docs.arangodb.com/3.12/release-notes/version-3.12/api-changes-in-3-12/#javascript-based-traversal-using-_apitraversal
You can reproduce this by running the python code from the readme:
from arango import ArangoClient
# Initialize the client for ArangoDB.
client = ArangoClient(hosts="http://arangodb:8529")
sys_db = client.db("_system", username="root", password="")
sys_db.delete_database("test")
sys_db.create_database("test")
# Connect to "test" database as root user.
db = client.db("test", username="root", password="")
# Create a new graph named "school".
graph = db.create_graph("school")
# Create vertex collections for the graph.
students = graph.create_vertex_collection("students")
lectures = graph.create_vertex_collection("lectures")
# Create an edge definition (relation) for the graph.
edges = graph.create_edge_definition(
edge_collection="register",
from_vertex_collections=["students"],
to_vertex_collections=["lectures"]
)
# Insert vertex documents into "students" (from) vertex collection.
students.insert({"_key": "01", "full_name": "Anna Smith"})
students.insert({"_key": "02", "full_name": "Jake Clark"})
students.insert({"_key": "03", "full_name": "Lisa Jones"})
# Insert vertex documents into "lectures" (to) vertex collection.
lectures.insert({"_key": "MAT101", "title": "Calculus"})
lectures.insert({"_key": "STA101", "title": "Statistics"})
lectures.insert({"_key": "CSC101", "title": "Algorithms"})
# Insert edge documents into "register" edge collection.
edges.insert({"_from": "students/01", "_to": "lectures/MAT101"})
edges.insert({"_from": "students/01", "_to": "lectures/STA101"})
edges.insert({"_from": "students/01", "_to": "lectures/CSC101"})
edges.insert({"_from": "students/02", "_to": "lectures/MAT101"})
edges.insert({"_from": "students/02", "_to": "lectures/STA101"})
edges.insert({"_from": "students/03", "_to": "lectures/CSC101"})
# Traverse the graph in outbound direction, breadth-first.
result = graph.traverse(
start_vertex="students/01",
direction="outbound",
strategy="breadthfirst"
)
