Many warnings in Moodle cronjob

[Richardvi]

I'm running Moodle 4.1.2 with latest Panopto plugin and see a lot of these warnings in the Cronjob log:

Execute adhoc task: block_panopto\task\sync_user_login
Adhoc task id: 10342

... started 20:10:54. Current memory use 20.8 MB.

The STDOUT constant is supposed to be built into the CLI environment so that you don't have to open the php://stdout handle multiple times. Seems a bit odd that it's failing, but the purpose is to print output. The var_export() is very odd, almost like the value being passed in is a very messy object, but it at least points us to problem.

Moodle-2.0-plugin-for-Panopto/lib/panopto_user_soap_client.php

Lines 121 to 122 in 857a85a

	if (!$this->usermanagementservicesync->SyncExternalUser($syncparamsobject)) {
	\panopto_data::print_log(var_export($this->usermanagementservicesync->getLastError(), true));

The SyncExternalUser function is failing. Now, I'm not sure why, and that's what the "getLastError" is supposed to be explaining, but there's probably a different problem like there's users on Moodle that are not on Panopto or the API call is failing.

Hi,

I have filed an internal work item to look into this issue.

Thank you for your patience,

We updated our test server to Moodle 4.3 and this is showing the same errors. I also see a new error, more or less the same as the old error.
