foreach() error in administrator/com_migratetojoomla/tmpl/check/default.php on line 51

[obuisard]

foreach() argument must be of type array|object, null given.

(reported by a tester, I do not have more information, sorry).

The error could be avoided by replacing:
$parameterformdata = @$data["frameworkparams"];
with
$parameterformdata = isset($data["frameworkparams"]) ? $data["frameworkparams"] : [];

[HLeithner]

if it really could be empty ok, but Null coalescing operator should be used with care.
if you use it use this one
$parameterformdata = $data["frameworkparams"] ?? [];
