Image files uploaded empty

Hi,

Short story: my developer does not respond anymore, I try to solve the problems myself.

This part should upload a ‘company’ CPT featured image but since March uplods an empty file instead.

My form fields:

[file companylogoupload id:logouploadfield class:logouploadfield limit:5MB filetypes:png|jpg]
[text uploadtextfield id:uploadtextfield class:uploadtextfield placeholder "hoose file..."]

The PHP which uploads it:

        if (isset($data['uploadtextfield']) && $data['uploadtextfield']) {
            $files = $submission->uploaded_files();
            $logoUpload = wp_upload_bits($data['uploadtextfield'], null, file_get_contents($files['companylogoupload']));

This last line gives this PHP Error:
[29-Jun-2021 07:30:01 UTC] PHP Warning: file_get_contents() expects parameter 1 to be a valid path, array given in /.../wp-content/themes/vallaltheme/functions.php on line 506

I hope there’s a simple solution for this. Either to give the array field or convert it to string?

Can you help please?
