我遇到了同样的错误(DF-ARG-007-仓库没有定义)。 在我的案件中,我要交出一个名字,其中仅举一字,引自“For-Each loop”(直线参数)管道的数据。 经过数小时的检查和测试,我现在责怪数据工厂可能将其内部编码。

Summary
The name field I needed to process contained a quote, e.g. "Miles O Brian":

Symptom
Inside monitor something like below is displayed (note the double-quotation of name):

{
"dataflow": {
    "referenceName": "PostProcessContact",
    "type": "DataFlowReference",
    "parameters": {
        "accountid": " 12345678-abcd-1234-abcd-123456789abc ",
        "name": " Miles O  Brian ",
        ...
    },
    ...
}

Job failed due to reason: com.microsoft.dataflow.Issues: DF-ARG-007 - store is not defined - source( ) ~> dummysource,EXE-0001,Dataflow cannot be analyzed as a graph,[564 737] DF-ARG-007 - store is not defined - EXE-0001,Dataflow cannot be analyzed as a graph, operation sink( ) ~> parentaccountid,[564 737]

Potential, related DF-activity
In the called flow I am using a dummy source without records as I want to build a record solely on the parameters given.

"source(useSchema: false,",
"     allowSchemaDrift: true,",
"     validateSchema: false,",
"     inferDriftedColumnTypes: true,",
"     ignoreNoFilesFound: true,",
"     format:  json ,",
"     fileSystem:  power-platform-dataflows ,",
"     fileName:  nuxnildummy.json ,",
"     documentForm:  singleDocument ) ~> dummysource",

Workaround
In my case, I was able to solve the problem by replacing the single quote in my input string with ‘ which is char(145). Not a nice solution but it works and I carry over the name just for reference.

// Previous Assignment: 
" @item()[ name ] ",

// Fixed Assignment:
" @{if(equals(item()[ name ], null), null, replace(item()[ name ],     ,  ‘ ))} ",

Conclusion
Although the workaround is OK in my situation, it is still a bad implementation, therefore @Microsoft:

• Would be great, if this issue will be addressed in a future update.
• Would be great, if an in-memory JSON source would be added which doesn t require one to create dummy-sources in Flowlets (e.g. casting an array of records like [{}, {}, ...] into a useable table).

I had encountered " DF-ARG-007 - store is not defined " , when passing a query statement created in Azure Synapse Piplines into Dataflow where extra " " get added like below :

Example : If statement is simple : " SELECT * FROM DBO.table " there is no issue

但是,如果说是声明的话,那么声明就是声明。

SELECT * FROM DBO.table WHERE ModifiedDate >=  1990-01-01 00:00:00.000 

转换成

" SELECT * FROM DBO.table WHERE ModifiedDate >=  1990-01-01 00:00:00.000  " -- notice 2 single quotes at the end

Solution

1. Before sending it to Dataflow convert SELECT * FROM DBO.table WHERE ModifiedDate >= 1990-01-01 00:00:00.000 to SELECT * FROM DBO.table WHERE ModifiedDate >= ^^1990-01-01 00:00:00.000^^
