Singapore InvoiceNow errors and warnings in Odoo: when they appear and what to do

Singapore InvoiceNow messages tell you what is missing or blocked: a PINT-SG profile, an Access Point, an exchange rate, the Peppol ID format or administrator rights. Below is each message exactly as the module writes it, when it appears according to its own wording and what to do. Several FlexigoTech Cloud messages state outright that nothing was sent, saved or deleted, so you can fix the cause before trying again.

How to read the messages on this page

Each message is shown exactly as the module writes it. Those starting with Only an administrator, as the text itself says, can only be sorted out by an administrator.

Where the text contains placeholders such as %s, %(ccy)s, %(date)s, %(names)s or %(other)s, you will see the actual value for your case instead. Read that value before changing anything: it tells you where the problem is.

If you have not configured the module yet, start with setting up Singapore InvoiceNow. This page is for when a message has already appeared.

Access Point keys stored in FlexigoTech Cloud

An Access Point can use a direct connection or go through FlexigoTech Cloud. Through FlexigoTech Cloud, the service stores the credentials encrypted, monitors the synchronisation and emails you if it fails. The messages in this part often end with Nothing was sent., Nothing was deleted. or by stating that nothing was saved.

MessageWhen it appearsWhat to do

Only FlexigoTech Cloud marks an Access Point key as saved: enter the key instead.You try to mark a key as saved by hand.Enter the key; only FlexigoTech Cloud marks it as saved.

Through FlexigoTech Cloud the Access Point endpoint has to be https://host/path, without port, user, query or fragment. Nothing was sent.The endpoint is not in the form the message requires.Enter the endpoint as https://host/path, with no port, user, query or fragment.
FlexigoTech Cloud keeps one Access Point key per authentication type and database, and %(other)s already has one. Delete that key first. Nothing was sent.There is already a key for that authentication type in that database.Delete that other key first.

In the messages about changing or deleting keys, the order they ask for is the same: first the key is deleted in FlexigoTech Cloud, then you change the type, enter the new key or delete the Access Point.

Where to look after a message

The InvoiceNow SG app gathers in its menus the PINT-SG profiles, the Access Points and an Inbound Errors list with the columns Move, Field Name, Raw Value and Reason.
