Comment:

 Hi there, welcome back to WordPress Trac! Thanks for the ticket.

 Replying to [ticket:54637 volodymyrkolesnykov]:
 > I see two possible ways to fix this:
 > 1. Ensure that `$iptc` and `$exif` are arrays — check the return value
 of the parsing functions, or
 > 2. Update the documentation/PHP doc blocks to mention that those
 parameters can be `false`.
 >
 > I can submit a patch for this issue, just not sure which of the
 solutions is preferred.

 I think I'd prefer the first option here, seems in line with a similar fix
 for `wp_generate_attachment_metadata()` in [51162] / #52603 (more details
 in comment:2:ticket:52603).
