Compatibility Issue with PrestaShop 8.1.5

[orlandopadillad]

trying to install using prestashop 8.1.5 I have the following issue

Cannot Install module printful. The version of your module is not compliant with your PrestaShop version.

I have the same problem but my prestashop version is 8.1.6

I have it working on PrestaShop 8.1.7, at least as far as I can tell; Printful support says it looks like it's talking to their system correctly too.

It took 3 changes to the Printful module:

• in src/services/web/WebserviceSpecificManagementPrintful.php

change:

public function setObjectOutput(WebserviceOutputBuilderCore $obj)

to:

public function setObjectOutput(WebserviceOutputBuilder $obj)

and change:

public function setWsObject(WebserviceRequestCore $obj)

to:

public function setWsObject(WebserviceRequest $obj)

• in printful.php

change:

        'max' => '8.1.3',

to:

        'max' => '8.1.7', 

EDIT: this is on PHP 7.3.33, by the way.
