API List Function Assistance

[jcawley]

Good afternoon all,

So I need help configuring a table referencing my API… I cannot get a list of elements to populate! I am receiving the following error:

"Expression.Error: We cannot convert a value of type Record to type Text.
Details:
Value=
379662=379662
396454=396454
396455=396455" ... etc etc

I believe I need to insert a List function (perhaps List.Distinct?), but I am not sure where to plug that into. I'm thinking perhaps part of Table.Transform. Anyhow, the API looks like this:

The function I am using looks like:

And the table:

Any help would be greatly appreciated!

Hi @jcawley 

I found some blogs and I hope they could help you solve your problem.

Blog1: Expression.Error: We cannot convert a value of type Table to type List

Blog2: Expression.Error: We cannot convert a value of type Record to type Text - source is List of records

Blog3: Expression.Error: We cannot convert a value of type Record to type Text.

What happens if you hard code that product # (that looks like a date?) into the url and run that M code as a query instead of a function, so you can see which step causes the error?  I am curious why you are using Record.ToTable, and suspect that is it.  Typically with REST API JSON responses such a step (and the transpose step) is not needed.
