Solved

Is there a mistake in this forEach to get all data by id. Using rule

a!forEach(
items: pv!id,
expression: a!save(
rule!Test_getDossierByDossierId(
dossierId: fv!item,
pagingInfo: a!pagingInfo(1, - 1)
),
pv!id
).data
)

I choose the first way because my rule!Test_getDossierByDossierId accepts one type rule input : dossierId

Brainy

Multiple:

- Using a process variable in an a!save() seems not correct

- What is that pv!id in line 8 doing?

- Querying data in a loop is a bad performing anti-pattern

In fact, I want to make a loop in a process variable "pv!id" to retrieve all data

Then just run loop like below, don't do a!save. Because you just need data

a!forEach(
  items: pv!id,
  expression: rule!Test_getDossierByDossierId(
    dossierId: fv!item,
    pagingInfo: a!pagingInfo(1, - 1)
  ).data
)

Or if you rule rule!Test_getDossierByDossierId accepts multiple type rule input dossierId then you don't need to run loop

rule!Test_getDossierByDossierId(
  dossierId: pv!id,
  pagingInfo: a!pagingInfo(1, - 1)
).data
