Hi,

I was trying to trace using savepiple to a file and restore from file but when i was tracing, popping up an exception at the restorePiplineFromFile step.

Could someone tell what might have gone wrong. Following is the error occured during trace.

Your inputs are greatly appreciated.

Hello All!

Any takers Please.

Thanks.

Here is the way to use SavePipelineToFile and RestorePipelineFromFile…

In the first execution of the service, enable SavePipelineToFile and set a name to the input variable, for ex. ‘TEST’. The data that’s there till this step in the pipeline will be saved to a file.

For further executions, disable ‘SavePipelineToFile’ and enable ‘RestorePipelineFromFile’ and set the same name as the input variable(TEST) that you assigned earlier to ‘SavePipelineToFile’ and then run the service.

PLEASE BE SURE TO DISABLE OR DELETE THE RESTOREPIPELINE FROM THE CODE WHILE MIGRATING TO QA AND PROD ENVIRONMENTS.

Thanks,
SATYA.

best way to achieve this is by using a branch step.

add a variable(say flag) in input/output
Branch on flag
flag=null then savePipelinetofile
flag=default then restorepipelinefromfile

This helps and you do not have to enable/disable any flow

But then you have to set a flag…isn’t that more clicks that a disable/enable (5 vs 3)?

Do you get an error when you restore the pipeline and step through but NOT when you restore and just run? I have seen operations where that was the case (specifically when uploading a file via a web page).
