avatar

 

Hi @MattWho , @pvillard 

I just found another bug in the 2.0.0 M3 release when I was trying to view the content of flowfile where it shows the following screen instead:

SAMSAL_0-1718305953316.png

When I check the log I found the following:

It seems from the error that its expecting a formatted content but it was getting something else. In my flow I notice this happen when I do ReplaceText to change the content of flowfile from json to sql script, so I was able to replicate using the following flow:

SAMSAL_1-1718306296011.pngSAMSAL_2-1718306321002.png

 

{
   "type" : "record",
   "namespace" : "Tutorialspoint",
   "name" : "Employee",
   "fields" : [
      { "name" : "Name" , "type" : "string" },
      { "name" : "Age" , "type" : "int" }
   ]
}

 

 

SAMSAL_3-1718306387058.png

 

 

exec DISC_INGEST.sp_IngestDisciplineTemplate
''
,'715B36EE-9D2F-43C7-A2D6-1044CAFCBF30_P2108.xlsx'
,'Test'
,'Estimating Template'
,'EstimatingTemplateTable'
,''

 

 

Click list queue from the ReplaceText success rel , then view content and you will get the error above !

As a workaround Im able to download the content successfully though.

By the way can I submit these issues in github? it seems the developers are more engaged there , however I dont see an option to submit issues there.

Thanks
