Transfer files (with an API) error message

[Bethany_Duffy]

Hi,

I have a workflow where I use an API to obtain the latest land and property data from the gov.uk website. The data is updated every month and so I need to re-execute the component containing the GET request each month.

This has been working since April, however for some reason I am getting an error message when trying to retrieve the November data. The API itself obtains the file path, latest dataset name, etc. but I am getting an error message on the Transfer Files node saying “the specified file ccod/CCOD_FULL_2024_11.zip does not exist”. I have checked the gov.uk website and their API tech details but doesn’t say anything has changed with the naming so slightly baffled!

Would anyone be able to point me in the direction of what might be going wrong here?

Thanks,
Beth

Hi @Bethany_Duffy , is there any chance you could upload details of the actual api calls you are making or better still the actual Workflow?

Without more information it’s difficult to guess what the problem is.

If you look in your file explorer, do you see any files at all, with maybe a slightly different name?

Also what is the full URL of the file it is trying to transfer?

Hi,

Thanks for the reply. Here are some screenshots from the GET requests and variables leading in to the transfer files node. All the info seems to be feeding from the API calls ok but the file just isn’t wanting to be read!

What makes it even stranger is that this used to work ok and a handful of audit teams aren’t facing any issues… just I can’t run it and the majority of others.

The base URL is https://use-land-property-data.service.gov.uk/api/v1/datasets/ccod

First GET request:

Second GET request:

Variable leading to the transfer files node:

Hi @Bethany_Duffy ,

Can I assume that you have a valid authentication key/token for accessing the API. If I click the link you posted, I get this message:

Is it possible that you had an API Key that has expired, which is why it has suddenly started to fail?

(From what you say, it looks like you get beyond that but I want to rule out the simple stuff first )

Hi,

Yes I do have a valid key.
