Subreport error: Exception: Error fill report: Erro fill internal

[theywc]

I have attempted several methods to generate the report, but the report with subreports has not been successfully produced. Below are two methods I have tried and the error messages. Please assist in providing a solution or an example.

Describe the bug
Jaspersoft Studio: Subreport OK!
Pyreportjasper: Subreport get some error

PyReportJasper setting:

1. Method1
   pyreportjasper = PyReportJasper()
   pyreportjasper.config(
   input_file,
   output_file,
   db_connection=db_connection,
   output_formats=output_formats,
   parameters={
   "start_date": '2024-01-01',
   "end_date": '2024-01-31',
   },
   locale='en_US'
   )
   Error Message(Method1):
   Exception: Error fill report: Erro fill internal: net.sf.jasperreports.engine.JRException: Resource not found at:

2. Method2: add resource
   pyreportjasper = PyReportJasper()
   pyreportjasper.config(
   input_file,
   output_file,
   db_connection=db_connection,
   output_formats=output_formats,
   parameters={
   "start_date": '2024-01-01',
   "end_date": '2024-01-31',
   },
   locale='en_US',
   resource=RESOURCES_DIR
   )

Error Message(Method2):
Exception: Error fill report: Erro fill internal: net.sf.jasperreports.engine.JRRuntimeException: net.sf.jasperreports.engine.JRException: Error loading object from InputStream.

Jrxml (subreport part):

<reportElement x="0" y="10" width="555" height="160" uuid="f68d53f9-b8fb-44d8-a261-419ead1f551c">
	<property name="com.jaspersoft.studio.unit.width" value="px"/>
	<property name="com.jaspersoft.studio.unit.height" value="px"/>
</reportElement>
<subreportParameter name="start_date">
	<subreportParameterExpression><![CDATA[$P{start_date}]]></subreportParameterExpression>
</subreportParameter>
<subreportParameter name="end_date">
	<subreportParameterExpression><![CDATA[$P{end_date}]]></subreportParameterExpression>
</subreportParameter>
<subreportExpression><![CDATA["TEST_sub1.jrxml"]]></subreportExpression>

Questions:

1. about setting, where should I correct?
2. is there any document for subreport for pyreportjasper 2.1.3v?

We have released version 2.1.4, which implements data typing for parameters sent to the reports. Please try using the new version and let us know about your experience.

Here's the link to the example: link

How to use:

import os
from pyreportjasper import PyReportJasper

def report_with_params():
    try:
        RESOURCES_DIR = os.path.abspath(os.path.dirname(__file__))
        REPORTS_DIR = os.path.abspath(os.path.dirname(__file__))
        input_file = os.path.join(REPORTS_DIR, "myteste2", "params.jrxml")
        output_file = os.path.join(REPORTS_DIR, "myteste2",  "output_file")

        pyreportjasper = PyReportJasper()
        pyreportjasper.config(
            input_file,
            output_file,
            output_formats=["pdf"],
            parameters={
                'myString': {
                    'value': 'TESTE STRING VALUE', 
                    'type': pyreportjasper.TypeJava.String
                },
                'myInt': {
                    'value': 1, 
                    'type': pyreportjasper.TypeJava.Integer
                },
                'myDate': {
                    'value': '11/04/1991', 
                    'type': pyreportjasper.TypeJava.Date, 
                    'format_input': 'dd/MM/yyyy'
                },
            }
        )
        pyreportjasper.process_report()
        print("Result is the file below.")
        print(output_file + ".pdf")
    except Exception as e:
        print(f"Error occurred: {e}")


report_with_params()

[jadsonbr]

We had an error processing subreports that was fixed in version 2.1.4.

Still have subreport issue. Not sure If I should set up config for subreport or not.
Please help to provide the jrxml example with subreport case. Thank you!
