I have come across a issue when I try to extract the items WI5 from the System 1 url (Data Scraping Part). The sequence does not appear to have any errors, however when I execute the entire workflow, I receive for this particular sequence an error stating that a constructor is missing and I am a bit confused as to why I need one in this case.
Attached is a screenshot of the error. I will try to reply to this post to provide screenshots of the data declaration arguments and variables as well as an overview of the sequence itself.
Hey @zahaman I am facing issue in System1_Extract_DataTable which assigning values. Refer error message. It seems data table not returning any values even I after I reset data on ACME System1 site. Will please help me to solve this issue?
Hey @PrankurJoshi, I am able to resolve issue by initializing data table but now I am getting below error message. Can you please help to understand where I made a mistake?
Hey @PrankurJoshi, It did giving me values but only when I declare dt_WIs and WIList both as variable. When I declare WIList as ‘DataRow’ as Output argument I am getting error message given in above/earlier post.
How can I pass this value to GetTransactionData workflow?
Still don’t under how can I pass variable in GetTransactionData workflow which I declared in Main.xaml? To do this, I may need to invoke Main workflow in GetTransactionData which doesn’t make any sense.
As per the Walkthrough document i did the changes in Main workflow and have below confusion. Can you please clarify on that too?
There is a conflict in what you have shown In Init State → System1_Extract_DataTable image showing In_WIlist as in argument and in System1_Extract_DataTable workflow is having out argument in both the locations it should be out_WIList argument. Do it step by step
Create out_WIList in Init State →
Go to System1_Extract_DataTable workflow create out_WIList argument
Assign out_WIList = WILIst in System1_Extract_DataTable workflow
Create local variable in Main.xaml WIList assign out_WILIst to WIList in InitState
Send WILIst as In argument in GetTransactionData as I shared in image
Actually I did assigned and created same variable in Init State → System1_Extract_DataTable but mistakenly I provided correct screen print. Sorry for that Here is the correct screen print.
After running Main workflow I am now getting this error message during processing ‘New Transaction’. Even I verified key in Config.xlsx and it is correct but still giving error. Don’t know what’s wrong.
As per the Walkthrough document i did the changes in Main workflow and have below confusion. Can you please clarify on that too?
This means that the Key you are trying to retrieve is not there in the Config.xlsx or when you have called InitAllSettings.xaml workflow it has not fetched any data from Config file
I did verified, key is available in Config file and also it fetched in InitAllSettings.xaml file from the Config file but still getting same error message. Refer screen print
Hey @PrankurJoshi, I re-verified the Config file and understood that the highlighted part in the key mentioned in screen print in not present in Config file hence it is mismatching and workflow getting failed. Now the question is how to handle it? Do we need to remove ‘TransactionNumber’ from the ‘Log Message’?
TransactionNumber is a variable which is declared in Main.xaml, try to do it without logging LogMessage_GetTransactionData then most of the part you are doing correctly
Hey @PrankurJoshi, when I am trying without logging LogMessage_GetTransationData (disabled activity), Main workflow is keep logging and opening System1 URL and SHA1Online URL and did not running process workflow due to below error message. Can you please help me to resolve this?
