Hi ​@Boglarka Barany 

What sort of provider are you using?

If you look at the error it seems to be a datatype conversion error. You can try to convert it to a nvarchar(max) to make sure it will be allowed to get in.

If you are using a CData provider there may be some issues besides this.

I am using the TimeXtender Hubspot connector. 

Hi ​@Boglarka Barany 

I don’t seem to have the locations endpoint you get this error on. Can you share how this is set up?

Locations is custom object for us in Hubspot, it is set up under the custom objects as per the TimeXtender input, here: 

If this is not what you are asking, could you please clarify what you would like to see?

Hi ​@Boglarka Barany 

Thanks, but adding these in my setup doesn’t make them appear as tables.

Do you see it in the metadata manager after synchronizing and if so what sort of fields does it show?

Hi ​@Boglarka Barany 

Do you have an update on Thomas’ question above? 

Thanks
