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

S

@SAMSAL 

This is some great detail.  I believe you are hitting this bug that has been fixed for the next 2.0.0 milestone release (M4):

https://issues.apache.org/jira/browse/NIFI-13329

There will eventually be a 2.0.0 RC release.  That will be the first official Release Candidate for new 2.x versions that will follow all these development milestone releases.  

You can create an Apache Jira account that would give you the ability to raise new issues you find directly in the Apache NIFi project.  This is best way to bring your finding to the developer community.

Please help our community thrive. If you found any of the suggestions/solutions provided helped you with solving your issue or answering your question, please take a moment to login and click "Accept as Solution" on one or more of them that helped.
