Column Shows in Postman but not in Power Query

[TCRUZ_MSFT]

Hi Experts,

I noticed that some columns inside the "attributes" of the response I got are not showing in Power query, but is showing in Postman. For context, the below screenshot shows a column named "isBookLevel" in Postman, which is field that I need to include in my current report.

In Power Query, I was able to expand all fields in the attributes column, but was only able to expand until the containerTagsourceID field, then the remaining fields no longer shows in Power Query:

attributes column

expanded attributes but only shows fields up to containerTagsourceID

I am using the same user credentials in both Postman and Power BI. Any suggestion to help me resolve this will be appreciated!

What is the type of data source and how are you connecting to it? Web.Contents or a more specific connector? Have you tried a more targeted query with a select-like query parameter?

Hi MarkLaf,

Thank you for the response. I was able to resolve the issue by adding api-version:4.0 in the call header, which I forgot to include in my POST call in Power BI.
