My app shows no error and runs and the flow runs without error but the above error pops up on the app side even though it seems a successful run. Here's my code:
TimeCardToPDF.Run("<!DOCTYPE html>
<html>
<body>
<br>
<b>"& "Name: " &" </b> "& txtTCName_1.Text &"<br>
<b>"& "Date: " &" </b> "& txtTCDate_1.Text &"<br>
<b>"& "Time On Job: " &" </b> "& Time(If(ddAmOnJob.Selected.Value = "PM",12, 0) + Mod(Value(ddHrOnJob.Selected.Value),12), Value(ddMinOnJob.Selected.Value), 0) &"<br>
<b>"& "Lunch: " &" </b> "& txtTCLunch_1.Text &"<br>
<b>"& "Time Off Job: " &" </b> "& Time(If(ddAmOffJob.Selected.Value = "PM",12, 0) + Mod(Value(ddHrOffJob.Selected.Value),12), Value(ddMinOffJob.Selected.Value), 0) &"<br>
<b>"& "Total Hours: " &" </b> "& txtTCTotal_1.Text &"<br>
<br>
<img src=" & JSON(penSignature.Image, JSONFormat.IgnoreBinaryData) & ">
</body>
</html>");
The email that arrives in my mailbox is just as it should be.
