Hi,

I keep getting this error when I try to connect to my shotgun site using the PDG Shotgun Session node.
The strange thing is that I did connect a few days ago, but now I can´t. Same problem on both machines, build 293, but same thing with 321. Perhaps is a windows update problem?
I can import the SG api in the command line tools with hython and in the python shell inside houdini, and connect to my shotgun site. Only with PDG I can´t.

It times out if the shotgun ‘server’ doesn't write to a specific temp file after a few seconds. The server is just a hython process. Could it be failing to write to your temp directory? You could take a look in the pdgtemp/log folder in houdini_temp or working directory to see if anything is written there.

Hello, I ask, the effect of the white hydrolysis calculator demonstrated in the new function of houdini17, provide engineering documents for reference? Is the engineering document of the water mist effect emitted from the top of the wave crest, where can I download it? Thank you!

Hi Chris, thanks for the reply.
No, Hython doesn´t save the file in the temp folder. I used a custom folder and the default folder. None of them worked.

Are there any log files in the temp folders? They may contain error messages.
Otherwise, could you please attach a hip file here or to a support bug for us to try to reproduce.

Hi Chris,

There is no file in the temp folder (although it creates the folder, but not the files).
I just used a simples file with a TOPnet with a Shotgun Session inside, nothing fancy.

The strange thing is: the example file in the docs worked at some point last week, but not anymore. And both computers had a Windows update going on after that, so I´m assuming is something related to that, could it be?

Are there some tests I could perform to try to narrow down the problem?

Try taking down your firewall if there is one up, sometimes windows update will re-enable it.

You could try running this little test of the shotgun python api in Houdini:

import shotgun_api3
from pprint import pprint
import os
SERVER_PATH = "https://creature.shotgunstudio.com"
def test():
    sg = shotgun_api3.Shotgun(SERVER_PATH, 
        login=os.environ['PDG_SHOTGUN_LOGIN'], 
        password=os.environ['PDG_SHOTGUN_PASSWORD'])

    # --------------------------------------
    # Find a Version by id
    # --------------------------------------
    fields = ['id', 'code', 'sg_asset_type']

    # --------------------------------------
    # Change this to the id of a Version in a project you have access to
    # --------------------------------------
    filters = [['id', 'is', 1027]]
    result = sg.find('Version', filters, fields,[], 'all', 0)
    pprint(result)

Hi Chris,

It works in the Houdini´s python shell. It works on hython too (with the command line tools).
I think it´s something in the pre-cook pass.

You could try running the rpc server manually at command shell, maybe there will be some errors:

"C:\Program Files\Side Effects Software\Houdini 17.5.300\bin\hython.exe" "C:\Program Files\Side Effects Software\Houdini 17.5.300\houdini\python2.7libs\pdgjob\shotgunrpc.py" --port 59685 --name test --temp_dir C:/temp --shotgun_url https://creature.shotgunstudio.com

Got a different error message.
The “error” in the beginning is from my pipeline scripts, but I already tested with default user preferences and got the same errors.

It seems to be complaining about Ctemp not existing. You can change that to a temp folder that you have.

sorry about that.
It worked.

the file “._pdg_shotgun_info_test” has this contents:
{"host": "Haroldo", "proto_type": "xmlrpc", "pid": 10148, "name": "test", "port": 59685}

and the log file “test_shotgunrpc” is empty.

Hi @chrisgreb,

Any thoughts about why it works everywhere, but not in the Shotgun Session TOP node?

Maybe worth trying with the most recent daily build? Can you run other TOP nodes ok? Otherwise if you like you could submit a hip file with a bug ticket and we could continue from there.

Thanks Chris. Everything else works as expected, just this node that is not working as (I think) It should.

I´ve submitted a ticket for this. Thanks for the help.
