Unable to translate bytes [AA] on account.account, Fabric Dataflow Gen2

I’m using the Bridge Online OData4 feed (bridge-online.invantive.com/acme-odoo1/odata4) in a Power Query / Fabric Dataflow to read Odoo.account.account@odo. The query is just a plain OData.Feed call, no $select, no filter.

It fails intermittently with:

Unable to translate bytes [AA] at index 0 from specified code page to Unicode.

Session-id: 86dc822b-5e1b-4ce0-be9d-7a59e2456842
Aanvraag-id: b10da8d5-3cec-4fca-8cc8-b0e2be7102fa

It doesn’t fail every time: same query, same row count, sometimes works and sometimes doesn’t a few seconds later. It seems to happen when paging past the first 100 rows. I also get this on the same table sometimes:

Invalid JSON.
Unexpected end of input was found in JSON content.
Not all object and array scopes were closed.

Verify correct server and user

Check carefully that you are logging into the Bridge Online website that is also used from Power BI and with the same user name. You will only see the requests from the Invantive Cloud user you are logging into the website with.

There are four servers in use:

  • bridge-online.cloud
  • app-online.cloud
  • bridge-online.invantive.com
  • app-online.invantive.com

You can see the server used in your script or source code of reporting.

Verify correct request and details

Please make sure to select the request to display the details. Only one single request should be visible in the screenshot.

Also check carefully that the request has a path with odata4 or apps. Other requests are in general non-relevant for this purpose.

Error message and tips per email

In addition, the Invantive Cloud user who has the error message will usually receive on his email address an email with an error message and tips if there is an error message in Power BI, Power Query, Azure Data Factory, Qlik or Tableau.

Advice is to check the affected user’s spam for such emails sent from support@invantive.com.
