Itgenoda184 Access to the OAuth data source requires a valid access token. The refresh token expired at ... and it is now

During retrieval or uploading of data with Exact Online you may get the following error:

itgenoda184
Access to the OAuth data source requires a valid access token.
The refresh token expired at … and it is now …

It is an error propagated from the Exact Online APIs:

invalid_request
The refresh token expired at … and it is now …

It indicates that an OData request was made by Invantive Cloud using a “long-lived” password (the so-called “refresh token”) to acquire a new short-lived password (the so-called “access token”). The times on the two ellipsises listed indicate the moments in time when the refresh token expired and the current time.

This error should not occur. Occurrence indicates an algorithmic failure in the communication between Invantive Cloud and Exact Online. However, when it occurs: please refresh your authorization as described in Eenvoudiger autorisaties vernieuwen op Invantive Cloud (Dutch).
