Error occurred when executing Int: object of type 'int' has no len()

[Mackay031]

Hi. I have been getting this error in a few of my workflows.

Error occurred when executing Int:

object of type 'int' has no len()

File "/Users/———/———/———/———/ComfyUI/execution.py", line 153, in recursive_execute
output_data, output_ui = get_output_data(obj, input_data_all)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/Users/———/———/———/———/ComfyU/ComfyUI/execution.py", line 97, in get_output_data
output_is_list = [False] * len(results[0])
^^^^^^^^^^^^^^^

Any ideas what may be causing it. I have had a look at execution.py but to be honest, I have no idea what I am looking for...

Thanks :)

Can you post the whole error from the console?

Hey, sure, here it is:

got prompt
ERROR:root:!!! Exception during processing !!!
ERROR:root:Traceback (most recent call last):

                               ^^^^^^^^^^^^^^^
TypeError: object of type 'int' has no len()

Prompt executed in 0.02 seconds

Also, interestingly. when I I tried to 'Update All' in Manager, I noticed this error in console:

Updating failed: /Users/———/———/———/———/ComfyUI/ComfyUI/custom_nodes/ComfyUI-AnimateDiff-Evolved
Cmd('git') failed due to: exit code(128)
  cmdline: git pull -v --rebase -- origin
  stderr: 'error: cannot pull with rebase: You have unstaged changes.
error: please commit or stash them.' 

I then tried Updating directly in the list and that seemed to go through. Not sure if its related. After the update, I ran the prompt again on that workflow and still received the original error at the top.

Thanks, Andy

I don't know if you've already resolved your issue, but if you still need assistance, post your workflow or at least a screenshot of it. Something is likely up with it

Hey, no it appears it is still an issue. I get this error, or at least the first part in most of my animation workflows:

ERROR:root:!!! Exception during processing !!! ERROR:root:Traceback (most recent call last): File "/Users/———/———/———/———/ComfyUI/execution.py", line 153, in recursive_execute output_data, output_ui = get_output_data(obj, input_data_all) ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

I can't seem to figure out any other custom node that is causing this. It appears a few people have posted this issue on the ComfyUI Github. Some say updating to latest versions of Nodes (including AnimateDiff Evolved) has helped them, but it hasn't worked for me.

Here is an example workflow I have just run to illustrate the issues:

Example_workflow.json

And this is the error message (I included everything after the progress bar):

In the above example, the error appears at the 'Image Save' node. However, as mentioned, errors have been appearing at other nodes in different workflows. Some examples:

Thanks for your time!!

Ps. I believe I am running the latest version of all custom nodes (including. AnimateDiff Evolved) and ComfyUI

Gonna assume this is long solved, closing.
