SQL Exception- Input Query Length Exceeding Maximum Limit in Dataverse Integration

(1) ShareShare
ReportReport
Posted on by EBMRay 1,710
Hello,
 
We are currently integrating using AppService to push data to Dataverse in a production environment, following this logic:
  • We retrieve data from an API to extract the customer's email and compare it with CRM.
  • If the account does not exist, we create the account.
  • We serialize the create/update lists separately.
  • Using a parallel "for each" loop, we send data in batches of 1,000 records per batch back to CRM APIs after generating the token.
  • We tried reducing the batch size to 10 records and even one record per batch and running the process without the parallel "for each" loop. However, in all cases, the calls are still failing.
When we trigger the process, the code fails with the attached error, suggesting that the query length is being exceeded. We have not found a way to catch which field is failing in order to increase its length.
 
Is there any investigation tool that could help identify the issue? We created a pre-validation plugin to check all field lengths, but it seems the plugin is not being triggered, indicating the process isn't even reaching the insert step in Dataverse.
 
Unfortunately, the customer cannot provide us with access to the production environment due to the sensitivity of their data.
 
Any assistance would be greatly appreciated.
Best regards,
Julien

    I am not getting anything from error. Maybe you can raise issue with MS, they will not support custom code but they can check logs from CRM side for you and if there is any issue captured then they can help. Also, as it is not working then you can think of another way to import your data. Like SSIS using kingswaysoft.
    One more thing, one time we faced this type issue, our  data migration using code working fine on non prod but it failed don prod. after investigation, we found there was some issue in data conversation. As our utility is hosted on the server and non prod and prod server are different so we faced this issue. you can cross check this also.

    Hi @ankit_signhal,
     
    Thank you for your valuable reply.
     
     We tried to investigate further and now we are facing a different issue as attached.

    We are not able to know which Task is Canceled. I think there is something wrong from the App Service itself. We tried on a different environment rather than the production and it is working perfectly.

    Hi,

    This is a generic error. Best way to replicate this issue on your non prod, if there is some sensitive prod data then you can munging/masking those data and use in non prod. we are following the same approach. 
    Or if this is not feasible for you then update your code. when you are fetching a record from your source use sorting and print some id or unique column in log one by one so you can check till which row your record is picked and inserted. when you got error then check the next record that should be bad data.

    Hello Ankit,

    Thank you for your prompt reply.

    As mentioned, the customer is not permitting us to analyze the data in the production environment. Based on our debugging and error handling, we are encountering the following exception:

    You can write the logs and then you can check where it failed and check that record.. Also, if it is custom code then run it in debug mode and analysis the data.
