Reading license file failed

[Veeraops]

Hi Team,

Below licensekey issue is coming while running docker command
sudo docker run -p 8085:8085 -e UNIHTML_LICENSE_PATH='/home/ec2-user/UnidocLicense.key' -e UNIHTML_CUSTOMER_NAME=Cashe_Software unidoccloud/unihtml

Err: reading license file failed: open /home/ec2-user/UnidocLicense.key: no such file or directory

We have UnidocLicence key and verified the license file's location, file permissions, and ownership, but still encountering the issue.
Could you please help us to resolve this issue as soon as possible.

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/

Hi @Veeraops,

This strange, probably can rename the file "UnidocLicense.key" into "UnidocLicense"? and try to remove the tick (') mark, so it will became like this

UNIHTML_LICENSE_PATH=/home/ec2-user/UnidocLicense

@sampila
Thanks a lot for the help and still we are getting the same error.
sudo docker run -p 8080:8080 -e UNIHTML_LICENSE_PATH=/home/ec2-user/UnidocLicense -e UNIHTML_CUSTOMER_NAME=cashesoftware unidoccloud/unihtml
Err: reading license file failed: open /home/ec2-user/UnidocLicense: no such file or directory

Could you please help us to resolve this issue

Hi @Veeraops,

Could you try this command on terminal

find $PWD -type f -name UnidocLicense

That will give result the path of UnidocLicense.

[Veeraops]

Hi @sampila
We have followed below actions
Checked the specified license file path to ensure it exists.

find $PWD -type f -name UnidocLicense
/home/ec2-user/UnidocLicense

Verified the file permissions for the license file.
Attempted to use alternate file paths for the license.
Unfortunately, these efforts have not yet led to a resolution. We believe that your expertise and guidance may be crucial in addressing this problem.

@Veeraops have you set the env variable for UNIPDF_LICENSE_PATH and UNIPDF_CUSTOMER_NAME?

[Veeraops]

@sampila
We have configured environment variables as well. But still persisting an issue
Please let us know the best way to proceed or any specific information you may require from our end.

@Veeraops

For now, we suggest you to use the UNIHTML_LICENSE instead,
The usage is like this

UNIHTML_LICENSE="full-content-of-license"

We will checks on our ends regarding the path issue.

[Veeraops]

Hi @sampila
Any update please to resolve this issue ?

[sampila]

Hi @Veeraops

Do this works fine?

UNIHTML_LICENSE="full-content-of-license"

[Veeraops]

Hi @sampila

While we were able to successfully run UniDoc using Docker and add content with a single command, an issue arose when attempting to connect to the UniHTML server at "http://XX.XX.XX.XX:8080/," resulting in the error message "invalid or no license provided."
Please let us know if you need any additional information from our end.

@sampila
After modifying the sample code provided in the Git repository, we attempted to use the following code snippet:
opt := unihtml.Options{"XX.XX.XX.XX", 8080, false, ""}
err := unihtml.ConnectOptions(opt)
However, we encountered a "context deadline exceeded" error.

Hi @Veeraops

Could you share a runnable code snippet? so we can debug this faster.
Like the html file you are trying to convert into pdf.

When looking at the error message, do you trying convert large html file?

Before attempting to convert a large HTML file, we are currently facing a connection issue with the UniHTML server.
Please let us know if you need any additional information from our end.

[Veeraops]

@sampila Can you please clarify us whether UniPDF license also covers the UniHTML plugin ?

[sampila]

Hi @Veeraops,

Looks like some network issue, seems the UniHTML docker is unreachable.

Yes the license should works with UniHTML.

and could you try to add this above the "main" function.

func init() {
  if err := license.SetLicenseKey(licenseKey, customerName); err != nil {
     panic(err)
  }
}

[Veeraops]

@sampila It's working as expected. Thanks for the support

[sampila]
