Hello,
please help. I wrote code below, but get error “Tag ‘image’ must be located within an image container.”
string base64ImageData = "";
string json = "";
dynamic jsonObject = JsonConvert.DeserializeObject(json);
jsonObject.imageData= Convert.ToBase64String(base64ImageData);
json = JsonConvert.SerializeObject(jsonObject);
Document doc = new Document(@"C:\Temp\in.docx");
ReportingEngine engine = new ReportingEngine();
JsonDataSource dataSource = new JsonDataSource(new MemoryStream(Encoding.UTF8.GetBytes(json)));
engine.BuildReport(doc, dataSource);
doc.Save(@"C:\Temp\out.docx");
have a nice day

@littlejacky There is <<image>> placeholder outside the textbox in your document. It is inside field. After removing it everything works as expected. See the corrected template: test.docx (20.9 KB)
Your template is fine, thanks for your reply 
json={arr:[{name,desc}]}
<<foreach [in arr]>>
<<if [desc]> //An error has been encountered at the end of expression 'desc]>'. Can not get the value of member 'desc' on type 'System.Data.DataRow'.
<<desc>>
<</if>>
<</foreach>>
@alexey.noskov Now i have another question. If there are some records in the arr collection in my json that do not have the ‘desc’ field. So how do I write a template to avoid errors?

@littlejacky There is a mistake in your syntax, instead of <<if [desc]> there must be <<if [desc]>>. Also, you can use ReportBuildOptions.AllowMissingMembers. If this option is set, the engine does not throws an exception when encounters a missing object member. Please see our documentation for more information:
