Power BI Paginated Report Err: Function 'PLACEHOLDER' encountered a Text that exceeds the maximum

[amyvanhorn]

Hi everyone, I had successfully created and deployed this power BI paginated report in the workspace environment for about 2 months, but now it stops working and gives me this error. Has there any updates/changes recently that messed with my report? Any idea how to fix this?

Error:

MdxScript(Model) (5, 5) Calculation error in measure '<ccon>SharePoint Images</ccon>'[<ccon>Display Image</ccon>]: Function 'PLACEHOLDER' encountered a Text that exceeds the maximum allowable length. (Microsoft Analysis Services)

------------------------------

Program Location:

   at Microsoft.AnalysisServices.AdomdClient.XmlaClient.CheckForException(XmlReader reader, XmlaResult xmlaResult, Boolean throwIfError)

   at Microsoft.AnalysisServices.AdomdClient.XmlaDataReader.BeginNewRow()

   at Microsoft.AnalysisServices.AdomdClient.XmlaDataReader.InternalRead()

   at Microsoft.ReportingServices.QueryDesigners.ASDesigner.QueryBuilderClientControl.QueryExec.ThreadExecution()

The error is for the DAX calculation of images that I turned into base64 and concatenated (this came from Power BI desktop but posted the calculation here):

 

Display Image = IF(

    HASONEVALUE('SharePoint Images'[Name]),

    "data&colon;image/jpg;base64, " &

    CONCATENATEX(

        'SharePoint Images',

        'SharePoint Images'[Pic],

        ,

        'SharePoint Images'[Index],

        ASC)

        )

Many thanks.

Thank you, the error was identified and resolved. One of the images was saved as a large size which broke the report.

Hi @amyvanhorn ,

According to your description, it seems like you got some error in your paginated report: the function 'PLACEHOLDER' encountered a text that exceeds the maximum allowable length. However, the report worked well before.  In order to make further troubleshooting, could you please provide the following info?

• Is there any recent changes have been made to the data or expression? If so, try reverting back to the previous version and see if the error still occurs.
•  Please check the length of the text being passed to the ‘PLACEHOLDER’ function and ensuring that it is within the maximum allowable length.

Best Regards
