Hash is not initialized

[rt97]

Hi everyone, I know this might have been asked a lot, but none of the solutions seem to work.

In my talend job I have the following

The readmessage component reads from the cachemessage component. however sometimes I get tHashInput_1 The hash is not initialized : The hash must exist before you read from it

Do you have any idea how can I add an initialization check?

Hello,

This normally happens when you are trying to read a tHashInput which do not have any content even though you have mapped it to a tHashOutput.

You are able to add a tLogrow before each tHashOutput to verify whether tHashOutput is getting right data or I will connect a tFixedFlowInput with the correct schema and zero rows to a Hash and then link all others to that to avoid this problem.

Hope it helps.

Best regards
