Error generating e-Invoice

Dhamu · April 2, 2024, 10:12am

Hi
I have configured the GST E-Invoice. I am Running ERP Next software from localhost Server.

When I am Submitting the Sales invoice During E-Invoice Generation shows following error.

ERROR:

Hello,

Your local server may not be connected to the internet and hence is not capable of being used for features that require internet connectivity - in your case generating the e-Invoice (these features require communication with the Govt. APIs).

Specifically, the DNS resolution is not happening as expected.

Hello @snv

Thanks for your reply.

My system is connected with Internet and I am browsing it. Any other issues?

snv · April 2, 2024, 11:25am

Hello,

Try this command in your terminal once, to ascertain if the DNS records are being received. If the command does not revert with one or more IP addresses, your DNS configuration may need fixing.

dig a +short asp.resilient.tech

You can also try resolving the DNS records of erpnext.com for comparison:

dig a +short erpnext.com

Dhamu · April 2, 2024, 11:31am

Hello,
I used the following command

dig a +short asp.resilient.tech

following is result

Also I Need to Clarify that I have Credit of 0 in my India Compliance Account. Whether above error is because of this credit.

Hello,

This means that your DNS servers are not configured correctly. Try this guide:

This is a separate issue. If you’re using sandbox mode, you don’t need credits. Otherwise, you may be required to make a purchase.

Dhamu · April 2, 2024, 12:48pm

Hello,

DNS Issue has been resolved and Working now. But Showing no Credits.

As you said I have set the Checkbox Sandbox Mode enabled and Triggered E-Invoice from Sales invoice. It generated successfully.
Sand Box Mode is for Testing API right. It won’t generate bill in E-Invoice Portal.
because I couldn’t receive IRN number while using Sandbox Mode.

snv · April 2, 2024, 1:16pm

Yes. Sandbox mode is only for testing. If you need to generate a real e-Invoice, please consider purchasing API credits.

Note: India Compliance API is freely available on Frappe Cloud.
