Using BodyPreview in Approval's details field display only part of the content
I am developing a flow, which will start an approval based on email received trigger. Received email is with HTML body (i.e. isHtml attribute is true). I want the body of the received email to be in Details field of Start and wait for an approval step. But, when I do like below only part of the body is assigned to the Details field.
In the approval mail, only 254 characters are displayed from a body with more than 1000 characters.
So, my questions is, are there any character limitations in setting up Details field of Start and wait for an approval step? I actually tried to assign a lengthy raw string (without getting it from BodyPreview) in to the Details field, this seems to work without any issues. Any help would be highly appreciated.
