Error on executing graph

yuri · March 16, 2023, 9:20pm

Good afternoon to all!
I am experiencing -I believe- a similar issue to some alreasy shared before. The source file printed with echo in a loop, shows that it is correctly identified. Any clues as to why this error (Error: [NodeId: Read] Specified ‘file’ [${sourceFile}] does not exist.) occurs would be greatly appreciated!

Please provide also your graph xml file and the batch file you are using. Also, the command to invoke the script would be helpful.

A guess is that you are specifying the source file with -SsourceFile= instead of -PsourceFile=.

It is similar as I expected.
The source product files is given as last parameter. This is somehow similar to the usage of -S.
For such a file a Read node is automatically added to the graph.

You graph expects a parameter on the command line which is named sourceFile.

You have two options. Change the command line call in the script to:

set procCmd=%gptPath% %graphXmlPath% -e -p %parameterFilePath% -PsourceFile= "!sourceFile!" -t "!targetFile!"

or remove the read node from the graph and change the Apply-Orbit-File node for the source product to:

<node id="Apply-Orbit-File">
    <operator>Apply-Orbit-File</operator>
    <sources>
       <source>${source}</source>
    </sources>
    <parameters>
...

yuri · March 17, 2023, 7:51pm

I have tried both options:

By only changing the command line call, I now get this error:
Error: [NodeId: Read] The 'file' parameter is not set

By only removing the read node and changing the Appy-Orbit-File node I get this error:
Error: Missing source '${source}' in node 'Apply-Orbit-File'

I also tried changing the <source> element of the Apply-Orbit-File node -in the part you suggested I changed- from <source>${sourceFile}</source> to <source>${sourceFile}</source> and get the same error: Error: Missing source '${sourceFile}' in node 'Apply-Orbit-File'

I really appreciate the time and effort you have spent both in making the Bulk Processing tutorial and to answer my queries.

marpet · March 20, 2023, 8:24am

When removing the Read node
Try this variation:

<node id="Apply-Orbit-File">
    <operator>Apply-Orbit-File</operator>
    <sources>
       <source>${sourceProduct}</source>
    </sources>
    <parameters>
...

I don’t see why changing the command line call leads to the “file parameter is not set” error.

Could you add
echo !procCmd!
before the line
call !procCmd!

This will print how the call finally looks like.
Please post the printed line.

This is already what is printed by SNAP/GPT and not what is printed by the script.

However, this shows that the parameter resolution is not provided in your property file.

Apologies for the late reply,
Indeed I had to define the resolution as you suggested.

Thank you for all your support, the processing now works!
