[NSFW] Security Error in CF7

Error Type : WordPress.Security.EscapeOutput.OutputNotEscaped
File : \wp-content\plugins\contact-form-7\admin\edit-contact-form.php
Line : Getting error in line 152
Error Message : All output should be run through an escaping function (see the Security sections in the WordPress Developer Handbooks), found ‘”onclick=\”this.form._wpnonce.value = ‘$copy_nonce’; this.form.action.value = ‘copy’; return true;\””‘.

Here’s an example of how you might fix the code:

$copy_nonce = wp_create_nonce('wpcf7-copy-contact-form_' . $post_id);
$onclick_attr = sprintf(
    "this.form._wpnonce.value = '%s'; this.form.action.value = 'copy'; return true;",
    esc_js($copy_nonce)
);
echo ' onclick="' . esc_attr($onclick_attr) . '"';
