Hi @RodneydeBeer ,
You can try the below points first that are often the cause of issues like the one you're experiencing.
The error (400) Bad Request with the invalid filter expression 'CreatedByUser eq@p' suggests that there is an issue with the syntax of the filter expression you are using in your API request.
To address this issue, please ensure the following:
1.Correct Filter Syntax: The filter expression should follow the Power BI API's expected syntax. A proper filter expression would look like Table/Field eq 'value'. For example, if you're filtering by a user who created a report, it should be something like:
CreatedByUser eq 'JohnDoe'
Replace 'JohnDoe' with the actual username you want to filter by.
2.Parameter Usage: If you are trying to use a parameter in your filter, ensure that you are passing the parameter value correctly. The @p notation is not recognized as a proper way to pass parameters in the filter expression for Power BI's exportToFile API. Parameters should be explicitly defined in the API call.
3.Check Field Names: Verify that CreatedByUser is the correct field name within the dataset you are trying to filter. If the field name is incorrect, the filter will not work.
