AI Builder 2020 wave 2, Form Processing, Tables returns null

Hi,

 

When using Ai builder on 2020 wave 2, Forms processing to extract data from invoices the tables are not properly recognized. and when trying to use data from tables in flows, the error: ExpressionEvaluationFailed. The execution of template action 'Apply_to_each' failed: the result of the evaluation of 'foreach' expression '@outputs('Process_and_save_information_from_forms')?['body/responsev2/predictionOutput/tables/Table_00ec9ba494b1c224c79726a1001cfd35d0/entries']' is of type 'Null'. The result must be a valid array comes up.

On AI Builder models,  Able to tag tables in  Tag Documents step, but when doing a quick test it wont recognize the tables. 

Also when analyzing the invoices the detected table excludes some rows of line data.

 

 

Thank you

Hi @kameshprsd,

 

A fix has been released that should have solved the issue with the model that you trained where it was not returning the table. Let us know if you still face issues.

Hi @kameshprsd,

 

Thanks for reporting this. We are currently investigating an issue where some tables are being returned as null. I will update this thread once a fix is released. 

Hi @JoeF-MSFT 

 

Thanks!

Hi @kameshprsd,

 

An update to this one. If you train a new form processing model, you should now get tables values returned. 

 

For your existing model, a fix will be released beginning of next week that will solve the issue.
