Unidoc 3.61.0 gives expired key error when using valid key

[JoeEdwards-GloveBox]

Sorry if this isn't the normal avenue for addressing such issues, but we have a production issue affecting our customers and so far [email protected] has been unresponsive.

We are a paying customer that seems to have an expired key. We receive the following error when trying to use unidoc: "unable to load unidoc license key: invalid license: The license has already expired.\nYou may need to update the license key to the newest license key for your organization.\nTo find your newest license key, go to https://cloud.unidoc.io and go to the license menu."

Trying to log into our account to fix the issue, via https://cloud.unidoc.io/login, we the following error message is displayed in the UI: Please activate your account first. Inactive User

Our key and account have been working up until a few days ago from what I can tell.

Please let us know how we can correct our account and key. Feel free to reach out directly via my email [email protected] and close the issue if you wish to take this discussion to a different venue.

EDIT:
We have confirmed that we are using a correct key. The issue seems to be limited to when we are using the latest 3.61.0 version. Using the same key with 3.55.0 seems to work fine.

Welcome! Thanks for posting your first issue. The way things work here is that while customer issues are prioritized, other issues go into our backlog where they are assessed and fitted into the roadmap when suitable. If you need to get this done, consider buying a license which also enables you to use it in your commercial products. More information can be found on https://unidoc.io/

I have updated the title and summary of this issue to reflect our latest research into this issue. If you use a valid key/customer name combo, this will fail using unipdf 3.61.0 and will succeed using unipdf 3.55.0.

Here is a little test script which you can use to test the bug:

package bug_test

import (
	"fmt"
	"testing"

	"github.com/unidoc/unipdf/v3/common/license"
)

// Example of an offline perpetual license key.
const offlineLicenseKey = `<LICENSE KEY>`

func init() {
	customerName := `<CUSTOMER NAME>`

	ofk := fmt.Sprintf("-----BEGIN UNIDOC LICENSE KEY-----\n%s\n-----END UNIDOC LICENSE KEY-----", offlineLicenseKey)

	err := license.SetLicenseKey(ofk, customerName)
	if err != nil {
		panic(err)
	}
}

func TestFunc(t *testing.T) {
	lk := license.GetLicenseKey()
	if lk == nil {
		fmt.Printf("Failed retrieving license key")
		return
	}
	fmt.Printf("License: %s\n", lk.ToString())
}

@JoeEdwards-GloveBox We tested your script using two different versions, and it's working well, confirming that the license is valid. If you encounter any issues with your license, please reach out to us through the customer portal, and we'll resolve it for you.

@ipod4g I've added the engineer who was experiencing this error on the support thread to help him narrow down the specific issue and why he's receiving the expired key message only when using this version of unidoc.
