The error seems to indicate that when the plugin tried to export a specific object, it ultimately couldn’t load that object. Then, when it tried to use the object, it was null, so the method saveXml() could not be called.
This is unlikely to be a PHP version issue. Rather, it will be a data/code issue. Specifically, the code is initially identifying an object (galley, submission, issue) to be exported, but then when it actually goes to export it, the object doesn’t load (perhaps because of inconsistent or invalid data).
My next step in this situation would be to identify which object was causing the problem, either by exporting one-by-one, or by debugging the code. Then, look carefully at the metadata properties for that galley/submission/issue. Is there anything odd about it?
In addition to @ctgraham’s comments here, I’ll mention that ultimately, the XML object that tries to get saved here is returned from the execute() method in lib/pkp/classes/filter/Filter.inc.php. You could try looking at the object there, or the $preliminaryOutput variable there, to see what you’ve got. As Clinton mentioned, if the resulting XML isn’t valid, you’ll get a null object.
As i understand if i use clean code of OJS 3.2.0-1, i should search database, and lookup where no data? Updating from 3.1.2.-4 was made by php-cli command.
I wouldn’t have an immediate guess of what to look for directly within the database.
If you are comfortable debugging PHP, you can use step-through debugging or error_log() statements to evaluate the variables along the call stack described in the error message, especially the XML @jnugent mentions.
If you are not familiar with debugging PHP, export the objects one-by-one in the interface until you encounter the error. Then, examine whichever object created the error directly within the submission system. Does anything stand out?
i have enable in config.inc.php
show_stacktrace = On
display_errors = On
i tryied from 1-st step, - creating and publishing issue.
i can create new issue, but when i try to publish it i receive:
[27-Mar-2020 18:52:32 Europe/Berlin] ojs2: Unrecognized DAO PublishedArticleDAO!
but when i change in DB setting “published” to “1” it became published.
I have create submission. it’s status is “Scheduled” but not “published”
my submission haven’t “locale” setting in “submission” table. i need to set it manualy. it has “null” before i change. also i change “status” from 5 to 3. and finaly it became published.
For the moment, I’d recommend disabling that plugin before publishing an issue (and re-enabling afterwards if you like). There will be an updated version of the plugin available soon in the plugin gallery.

i know that my hands grow from my ass… but i will lost my mind
I think that reference to Article is the problem – it changed starting with OJS 3.2.0 but it appears to not have been updated. Could you try the following two queries?
UPDATE filter_groups SET input_type = 'class::classes.submission.Submission[]' WHERE input_type = 'class::classes.article.Article[]';
UPDATE filter_groups SET output_type = 'class::classes.submission.Submission[]' WHERE output_type = 'class::classes.article.Article[]'
Please confirm whether that works and I’ll get it added to GitHub for the next release.

Great! I’ve filed and fixed the CrossRef issue here:
For the DOAJ issue, I think you’re encountering a firewall problem or something similar that’s preventing OJS from contacting the DOAJ website for part of the schema description. See this thread: OJS3 XML doc error

One with the DOAJ deposit process (Supplied data was not valid JSON), which I haven’t looked at yet, and
Another with the export XML (the invalid XML problem).
Can you confirm that you’re able to successfully perform both processes in OJS 3.1.2? Is your server behind a proxy, and if so, is it configured in your config.inc.php configuration file?
