`qibo-client` 404 error

[BrunoLiegiBastonLiegi]

Running the example shown in the readme results in a connection error.

I am using qibo-client/main. This is blocking some developments in qibo-cloud-backends (qiboteam/qibo-cloud-backends#20, qiboteam/qibo-cloud-backends#7) and qibo indirectly (qiboteam/qibo#1282).

@BrunoLiegiBastonLiegi thanks. I believe this is due to the new quota system, cc @marcorossi5.

This is due to the following lines:

https://github.com/qiboteam/qibo-webapp/blob/7edd2b389074650a4c3ce0d3574e235871f5ddd5/src/accounts/views.py#L84-L85

Both of try to access objects that are not present in the database. We should fix the fixtures to correctly load the objects in the database schema.

@marcorossi5 thanks, could you please take care of this and deploy the new website?

[BrunoLiegiBastonLiegi]

Hi, I noticed that a fix for this has been merged. However, I still get the 404 error by simply running the code example. I don't think it's due to my token being wrong, because the same error happens in qibo-cloud-backends main https://github.com/qiboteam/qibo-cloud-backends/actions/runs/8917928327/job/25510345685.

[scarrazza]

@marcorossi5 for completeness, please find below the circuit which is generating issues during the json encoding:

from qibo.quantum_info import random_clifford
from qibo import gates

circuit = random_clifford(3)
circuit.add(gates.M(0, 2))

[scarrazza]

This is now fixed in Qibo.
