kettle - Any idea about this weird type error in Pentaho Data Integration? -

-

i have :

insertion des données dans table some_table.0 - some_auto_generated_db_key integer : there data type error: data type of java.lang.boolean object [true] not correspond value meta [integer]

what boolean??? see boolean? have added trace writing step before failing inserting step, , see fine integer value of some_auto_generated_db_key .

how can possible? new kettle, if have idea or tips awesome.

here screenshot of transformation :

transformation

just before failed insert, have filter splits stream. on 1 half of stream, looks have add constant step. if i'm reading right, 2 inputs insert step don't have same fields in same order. few steps earlier, there similar splitting of paths goes off right, have same effect.

whenever remerge streams without being careful, strange errors can pop up. pentaho tries warn when create hop remerge streams, there ways miss warning.

suggestion: each time stream remerges, right-click on each of 2 previous steps, , have show output fields. compare 2 lists side-by-side verify same. if not, have add or remove fields appropriate make them same on both sides.
