Error PARAM_SIGNATURE: Invalid signature when posting an image using mediatopic.post (APIok) ???

Question

PHP

Question about working with APIok.
When publishing a media topic using the mediatopic.post method with an image *, an error almost always occurs:
Array ( [error_code] => 104 [error_msg] => PARAM_SIGNATURE : Invalid signature......
The reason for this error is the presence of a + "plus" symbol in photo_id (in attachment) which we get when uploading a file to the server ok, if there is no "plus sign" in the photo_id line, then everything works.
I would be glad for any help
