where are you getting this error? for which activity?
are you using any enumerable type variable’s value
it seems, the index used for a variable doesn’t exist.

To check try debugging the file and t the time of error, check local panel for all related variable’s value

Hi! @rahulsharma

I am getting this error from Extract data table from html activity.

UiPathTeam.ExtractDataTablesFromHTML.Activities This is the package i’ve used to extract the tables.

and this is the HTML text I am passing

v_mailMessages(0).Headers(“HTMLBody”).ToString

  Where v_mailMessages is a variable which is the type of System.Collections.Generic.List<System.Net.Mail.MailMessage>

Hi @THIRU_NANI

I Guess you re extracting datatable from html body!

Check with the count of mail and then proceed to extract the html table

And also check with the reference thread below!
