2 hours ago I found a similar issue and discussion that might be relevant to your problem:
- Error in item: Invalid variable (open) - This discussion addresses a similar issue with variables not being found.
- This is a major issue with parallel execution in the workflow (open) - This discussion talks about issues with parallel execution in workflows.
The issue you're encountering with the parallel workflow run failing in Dify version 0.8.3 is likely due to the query variable not being properly initialized or passed to the nodes that require it. Specifically, the nodes tt and tt-2 use the query variable in their template, but there is no evidence that this variable is being set or passed correctly during the test execution.
Here is the relevant part of the code where the query variable is expected:
{
"data": {
"template": "{{ arg1 }} 123",
"title": "template transform",
"type": "template-transform",
"variables": [{"value_selector": ["sys", "query"], "variable": "arg1"}],
},
"id": "tt",
},
{
"data": {
"template": "{{ arg1 }} 321",
"title": "template transform",
"type": "template-transform",
"variables": [{"value_selector": ["sys", "query"], "variable": "arg1"}],
},
"id": "tt-2",
}To fix this issue, ensure that the query variable is properly initialized in the VariablePool when the GraphEngine is instantiated. For example:
variable_pool = VariablePool(
system_variables={
SystemVariableKey.QUERY: "your query here",
SystemVariableKey.FILES: [],
SystemVariableKey.CONVERSATION_ID: "abababa",
SystemVariableKey.USER_ID: "aaa",
},
user_inputs={"query": "your query here"},
)Make sure to replace "your query here" with the actual query you want to test with. This should ensure that the query variable is available to all nodes that require it, preventing the variable not found error [1][2].
