TypeError when trying to submit payment form

[chlsydkysr]

Description

I migrated to Craft 4 & Commerce 4 and wasn't able to place orders with Mollie as gateway.
When submitting the payment form, I receive the following error message:
TypeError
craft\commerce\omnipay\base\RequestResponse::getRedirectData(): Return value must be of type array, null returned

I noticed that the function "getRedirectData()" in omnipay/mollie/src/Message/Response/FetchTransactionResponse.php currently returns null. When changing this to return $this->data, I am able to submit the payment and everything works again as suspected.

Additional info

• Craft version: Pro 4.4.5
• PHP version: 8.0.27
• Database driver & version: MySQL 5.7.40
• Plugins & versions: Mollie for Craft Commerce 4.1.0

Same issue here.
First opened an issue at the Commerce repository: craftcms/commerce#3126

This should be fixed in commerce-mollie 4.1.0.1 - Please update and let us know how it goes.
