aerender fails on Mac OS 11.4 with error -1701 "AEGetParamPt failed at line 918"

[hdngr]

EDITED

For all who come next. To be clear, this is a problem with AE Render and the newest OS Security Updates, not nexrender. My best guess is it is how AE Render uses it's websockets interface to communicate across the machine - kind of squirly and open ended with AE Render sending/receiving requests from the After Effects process.

Describe the bug
After upgrading to newest MacOS patches aerender chokes.

Seems to be a permissions issue where aerender cannot open After Effects.

Solution:

1. Open After Effects with any project, or no project at all - just make sure the process is open and running
2. Pass -reuse flag to aerender:

# If using nexrender programatically: 
{
...
aeParams: ['reuse'],
...
}

#Or, if via command line:
>> nexrender [other params] --reuse

Via command line:
nexrender ... --reuse

unfortunately I cannot get the --reuse working as mentioned. You use it like this?
./nexrender-worker --reuse --host=***** --secret=*****

@stevenzielke You need to open After Effects Render Engine before running your nexrender-worker.
Hope this helps !

reuse here doesn't work for me as I'm getting aerender ERROR -1712: AESend failed to send apple event at line 909 instead when setting the reuse flag.

Do you already have AE Open and Running? Try it with AE Already open and running, and then AE Render will using the existing process and not throw an error. That is what I and other user's are having success with.

[limzykenneth]

Yes, I'm sure I have. That's the error it is giving.

Not using the reuse flag give error -1701 "AEGetParamPt failed at line 918" you mentioned in the original issue, using the reuse flag with AE already open and running gives ERROR -1712: AESend failed to send apple event at line 909.

There is a same bug in AE&&Mac OSX.

I got an update from Adobe in the support forum - the issue has been fixed in the latest version of After Effects Beta, v22.0.0x94 (note that this is different from the stable version). I've tested it with my own install of nexrender on Catalina, and it works fine as it did before the security update broke things.

So an alternative for now if reuse=true is inconvenient or not an option is to install the AE Beta separately. A couple of caveats: first the AE Beta uses its own distinct settings from the stable release so you will need to re-enable "Allow Scripts to Write Files and Access Network" in After Effects preferences if your scripts rely on that. Second, you will need to explicitly set binary to the path of the After Effects Beta in the options when initialising nexrender rather than relying on autofind to pick it up.

Thanks for this, I've been running into this issue and racking my brains about how this has occurred.|

Now I know
