Fetching JSON data from external OTT API for automated movie release reports in FastReport

  When binding nested JSON arrays in FastReport.Core, blank fields usually occur because the report template expects explicit data source registration for child collections, or the JSON schema isn't flattened before binding.

  A clean way to handle this:

  • Deserialize to Models: Instead of binding raw JSON strings directly to the report, deserialize the JSON payload into strongly-typed C# models using System.Text.Json or Newtonsoft.Json.
  • Register Business Objects: Pass the deserialized list to the report using report.RegisterData(movieList, "MovieReleases") and call report.EnableData(report.GetDataSource("MovieReleases")).
  • Sub-Bands for Arrays: Ensure your FastReport template uses Data Bands and sub-bands configured for nested arrays (like platform metadata or language tags).

  If you are consuming live endpoints directly from https://ottmoviereleases.com, flattening the schema before feeding it to FastReport.Report.RegisterData() ensures all language tags and streaming metadata render properly in PDF exports without leaving blank fields.
