Hi @Tamilselvan ,

i am getting exception while rendering the response , so below are the steps i am performing during design

  1. Create base 64 string from image using Invoke code

2.Pass that base 64 string code to Form activity as Argument

  1. Specify sampleimage variable inside content field of Dynamic html component

While execution when base 64 variable is getting passed to form activity i am getting this exception

here is the base 64 string for refrence :

here is the code which i am using to generate base 64 string

Dim imageArray As Byte() = System.IO.File.ReadAllBytes(“C:\Users\ygarg\Documents\UiPath\OracleEBSAPAutomation\PDF Attchements\20191120\1.jpg”)
base64ProcessImageRepresentation= Convert.ToBase64String(imageArray)

Got the same error. What i do:

  1. Assign: imageArray(byte) = System.io.file.ReadAllBytes(“C:\Users\mustermann\Documents\UiPath\IntelligentOCR\image.jpg”)
  2. Assign: base64ImageRepresentation (str) = convert.ToBase64String(imageArray)
  3. CreateForm with html element and html content: “<img src={{data.sampleimage1}} height=100 width=100 >” (edited the end of the html code usually it’s /> at the end)
  4. FormFieldsCollection in Create Form activity: As in-Argument “sampleimage1” as str and value = base64ImageRepresentation

The image is not shown when the form opens and sometimes the robot executor crashes.

Any advice?

Found the solution for that in this forum post: Html Img Source only works with http location and not local folder
