I have builded a [workflow](https://app.roboflow.com/workflows/embed/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ3b3JrZmxvd0lkIjoiWVlXSm9YcFJ0MmpYUm5KVGRPeVgiLCJ3b3Jrc3BhY2VJZCI6InZjQmw1Y0x3bUtQallLTGNRemV1VkE4UlRhNjIiLCJ1c2VySWQiOiJ2Y0JsNWNMd21LUGpZS0xjUXpldVZBOFJUYTYyIiwiaWF0IjoxNzcwMjgzMTEzfQ.jgWKGz18MfANPMn7IsRxTyUHicePU3TLb4WPNX5ZYqM) with Qwen2.5 VL block. When I run this workflow on GPU, I get following error:

```auto
Workflow references '$steps.qwen2.5_vl.parsed_output' which points to a non-existent block.
Blocks with errors:
1.
output
Error in output: output_1. Invalid reference to $steps.qwen2.5_vl.parsed_output.

```

The screenshot is attached below.

Please help with this as I am not able to use the Qwen2.5 VL block in my workflow.

Hi @Timothy_Malche , looking into it, seems like the issue is the `.` in the name (`qwen2.5_vl`), could you rename the block to eg `qwen`?

Note that neither serverless nor dedicated deployments will be able to run such a large model at the moment, but we are working on improving Serverless offering (likely) this month to also support larger models (like qwen).

Thanks, Erik
