Hi @nikulsynoptek, thank you for reporting this issue! I have created an issue to investigate this internally and someone will follow up with findings or if any additional info is required.

In the meantime, are you be able to provide us with any other environmental or implementation details that might be helpful when trying to reproduce the issue, like what version of PHP are you using? What edition of Magento 2.3.1 (i.e. CE, EE) are you using? Any shipping extensions or custom plugins being used, etc.

Thank you!

Hello again @nikulsynoptek,

My apologies that I didn't realize immediately, but looking at Magento's system requirements here, if you are using v1.4.9 of our extension this issue is likely environmental.

If you were trying to upgrade to latest (which at the time would've been v1.7.1), you will need to be using PHP 7.3 or greater and upgrade to from Magento 2.3.1 -> 2.3.3 to be able to upgrade our module version to at most v1.7.1. Also, with PHP 7.3 recent EOL, to upgrade to v1.8.0 (current latest release) and onward, minimum system requirements are now PHP 7.4 and Magento 2.3.7 or greater.

Hi @nikulsynoptek, I'm going to close this issue for now, but if upgrading to compatible versions of Magento and PHP does not resolve your issue, please reopen this issue or reach out to our expert support team at support@taxjar.com!
