Hiya

Found a few issues with the above error message, but none of the resolutions of those issues have helped me.

Details:
macOS Sierra
php v7
node v6.9.1
npm -v4.3.0

It's a WordPress site and the file that seems to be causing it to fail, has the path of: file:///Applications/MAMP/htdocs/fw/wp-content/themes/fw/includes/functions/advanced-custom-fields-pro/admin/admin.php

Just installed VSCode this morning and willing it to work, but this problem keeps popping up?

Hoping you can help...Thank you!

Maybe same here on Win10, I wrote an issue #326.

[Alenore]

I've posted a temporary workaround in the issue referenced by designcraft, if need be. :)

[iaremarkus]

@Alenore you beautiful thing you 🥇

[Info - 8:20:30 AM] All 118 PHP files parsed in 4 seconds. 70 MiB allocated.

@felixfbecker Is this a 'fix' worth including in your next version?

[felixfbecker]

@wondergryphon As I already said on the other issue, the root cause is that type was set to null, not that the null value isn't handled. I appreciate any PR that gets to the bottom of this

[john-landgrave]

I tried manually applying the fix that @Alenore posted in that other bug, but the language server is still crashing on me. Is there some magic I'm supposed to do to rebuild or reload the extension? Or should the good old power cycle handle that?

[nonameolsson]

I get this problem both on Mac and Window at least 20 times a day.

[felixfbecker]

Is this still an issue with the latest version?
