Hi All,

BC v19.02, W1
installation: OnPrem deployment


error: RDLC cannot be opened since error pops "Data at root level is invalid. Line 1, position 1"

description: I am trying to create RDLC layout for a custom report, but as I click on the custom report object file in File Browser of my project in AL, and select "Open Externally", the ReportBuilder opens as expected, but error pops:
Failed to open 'Report 50000 - Employee Tools.al'
"Data at root level is invalid. Line 1, position 1"

This happens for any custom report.

    Issue resolved.

    I was trying to open the report in the Report Builder from the *.AL file, instead of *.RDLC file.

    Thanks Damjan
