Incorrect signature/stub used for XMLWriter::startElementNs

[aboks]

According to the PHP documentation the 1st and 3rd parameters to XMLWriter::startElementNs() accept string|null; see https://www.php.net/manual/en/xmlwriter.startelementns. However, Psalm complains when null is passed as an argument to this method: https://psalm.dev/r/216f3978ac.

Unfortunately I cannot find where Psalm infers these method signatures from; they don't seem to be in the /stubs folder. I would be happy to check and correct the method signatures if I know where to find them.

I found these snippets:

https://psalm.dev/r/216f3978ac

<?php
$xw = new XMLWriter();
$xw->startElementNs(null, "foo", null);
$xw->endElement();

Psalm output (using commit 09b0167):

ERROR: NullArgument - 3:21 - Argument 1 of XMLWriter::startElementNs cannot be null, null value provided to parameter with type string

ERROR: NullArgument - 3:34 - Argument 3 of XMLWriter::startElementNs cannot be null, null value provided to parameter with type string

It's in https://github.com/vimeo/psalm/blob/master/dictionaries/CallMap.php

Thanks! I will try to make a PR with checked/updated XMLWriter stubs somewhere in the next week.
