Node not existing upon ia.start()

[Karptinius]

Describe the Bug On harvesters 1.3.6 when I try to start the acquisition with ia.start() or ia.start_acquisition(), I get the following error: Exception has occurred: AttributeError, Node not existing (see below). The error is not present if I revert to harvesters 1.3.2.

To Reproduce See code below.

Sample Code I can show a piece of code that demonstrates the reported phenomenon:

• [X] Yes
• [ ] No

h = Harvester()
h.add_file(path_to_gentl_cti_file)
h.update()
ia = h.create_image_acquirer(list_index=0, file_path = path_to_GiGE_description_xml_file)
ia.start()  # ia.start_acquisition()

If applicable, please paste the actual output (its whole tracebakc, etc) here:

Expected Behavior Start acquisition without issues.

Configuration

• OS: Windows 10
• Python: 3.8.13
• Harvester: 1.3.6
• GenTL Producer: mvIMPACT Acquire 2.46.2, MatrixVision
• Camera: Custom (GiGE description attached)

Reproducibility

This phenomenon can be stably reproduced:

• [X] Yes
• [ ] No.

See the code above.

Actions You Have Taken

Reverted back harvesters version to 1.3.2.

• [X] I've read the Harvester FAQ page.

@Karptinius Hi, thank you for the report. The issue has been fixed by #332 in the master so you can give that a try but I have not yet released the fixed version so it's not available at PyPI, either. I am planning to release it in the following days and will let you know once it's released. Thanks, Kazunari.

Hi @kazunarikudo, thank you for your answer and sorry to create a duplicate... I'll be looking forward to it ! And a big thanks for this great harvester which helps me a lot.

[kazunarikudo]

Please do not worry about that. Everything should have been fine if I had released it as soon as possible. Anyway, I am glad to know you liked Harvester.

@Karptinius Hi, I have just released version 1.3.7 and you can install it by executing the pip command. Feel free to create another ticket if it does not work for you.
