Many error messages after update from EE5 to EE6.4.6

Question

I am seeing many error messages post-update from EE 5.x.x to EE 6.4.6. They go away if I revert back to PHP 7.4 from PHP 8.1. All add-ons (just Wygwam and ChannelImages) are up to date. Dreamhost server. Any suggestions greatly appreciated (previous list of error messages removed for clarity).

UPDATE: Thanks eeharbor for supplying the new ChannelImages update (7.5.2) this made the error messages I was seeing when saving an entry go away. However, I still am seeing the following error messages on multiple sites that I updated from EE version 5.x.x to 6.4.6, with PHP version set to 8.1:::

Answer 1

A new release of Channel Images: 7.5.2 has been released to fix this. Thank you for your patience as we update our addons to php 8.2

Answer 2

This looks like a problem arising in the Channel Images add-on - see the lines

Deprecated
parse_str(): Passing null to parameter #1 ($string) of type string is deprecated

user/addons/channel_images/api.channel_images.php, line 596

    Severity: E_DEPRECATED

Deprecated
parse_str(): Passing null to parameter #1 ($string) of type string is deprecated

user/addons/channel_images/api.channel_images.php, line 596

    Severity: E_DEPRECATED

It looks like these issues then trigger a cascade of other issues.

Channel Images claims to be php 8.2 compatible in the latest version (7.5.1) - so if this error is happening and that's the version you are using I think you should get in touch with eeharbor to see if they can resolve it for you.

HTH.
