Python Data Function Extension: Temp file not found

[Todd Cray]

I've installed the Python Data Function Extension (1.3.1, but also tried 1.3 and 1.2.1 with same results)on SF 10.6. Using Python 3.7.9 and PIP'ed Pandas and NumPy, as required.

As a first test, I am trying to run the GroupBy.dxp sample that came with the Extension. This example takes two columns from an input file, performs three lines ofvery simple PY code and outputs a new data table with three columns. Instead of a result, I am getting an error message: File not found ...TemptmpA335.stdf (this file name changes as I re-run the PY Data Function):

Could not execute function call 'GroupBy'

File not found: C:UsersAdministratorAppDataLocalTemptmpA335.stdf

at Spotfire.Dxp.Data.Import.FileDataSource..ctor(String filePath, String[] additionalFilePaths)

at SpotfirePS.DataFunctions.Python.PythonDataFunctionExcecutor.d__4.MoveNext()

at Spotfire.Dxp.Application.Extension.CustomDataFunctionExecutor.d__5.MoveNext()

at Spotfire.Dxp.Data.DataFunctions.DataFunctionExecutorService.d__7.MoveNext()

When examining the Temp directory, I discover that an stdf file was created of the two columns from the input table. But just as the error suggests there is no stdf file by the name tmpA335.stdf. I assume that this one would have been the output from the PY code.

A while ago, a similar error was discussed here. In that case, the solution offered read: "The file not found error occurs whenever there is a mismatch between the parameters defined in Edit Script and those used in Edit Parameters.Checking required parameter is a handy safeguard for this."

However, this does NOT appear to be the problem here. For one thing, I am using--without any modifications--a TIBCO-provided sample that obviously worked before (as Ican see in the DXP, a proper output table had been generated on a previous run). For another, as I test with even simpler examples (such as: Using no input at all, output one single value to a Document Property) the same error keeps recuring.

 

I know that the Python Data Function Extension became obsolete with SF 10.7 native PY support. However, a migration at this time is not an option. Please help!
