CyREST : Problem in my function to copy a network

[Pascal KREZEL]

Hi,

I made the following function to copy a network:

def copy_network(net,collection="Recon2",name="copie"):

    SUID=net.get_id()

    netId=cy.network.create(suid=SUID)

    net2=cy.network.create(suid=None,data=netId.to_json(),collection=collection,name=name)

    return(net2)

Normally it works but now it fails with the following error :

---------------------------------------------------------------------------
HTTPError                                 Traceback (most recent call last)

      1 # Copy of recon2

      5     return(net2)

HTTPError: ('412 Client Error: Precondition Failed for url: http://127.0.0.1:1234/v1/networks?collection=Recon2', 'Could not parse the given network JSON.')

What can I do ?

Hi.

Do you have a small network example to reproduce this copy problem?

Thanks,

Kei

Hi, Kei,

Thank you for your answer.

I tried to replicate the problem this morning but with my new notebook it doesn't happen any more.

There is an instability.
