Since two days our pipelines start failing once in a while with the same error throughout - the TokenLibrary seemingly randomly does not work anymore.
TokenLibrary.getSecret(keyvault_name, key_name, keyvault_linkedservice_name)
Error log:
Py4JJavaError: An error occurred while calling z:com.microsoft.azure.synapse.tokenlibrary.TokenLibrary.getSecret.

Hi @Victor Seifert ,
Thankyou for using Microsoft Q&A platform and thanks for posting your question here.
As I look into the issue you are facing , It seems synapse notebook is throwing error when you are trying to retrieve a secret stored from Azure Key Vault. The same was working fine earlier . Please let me know if my understanding is incorrect.
I would be taking this forward to our internal team to understand if there is any deployment responsible for this error you are experiencing. However, meanwhile, I want you to make sure the following permissions are all set at your end. Kindly make sure :
Looking forward to your response. Thanks.
"It seems synapse notebook is throwing error when you are trying to retrieve a secret stored from Azure Key Vault. The same was working fine earlier ." > Yes. That is correct. We get these errors seemingly at random in scheduled-triggered pipelines.
Hi @Victor Seifert ,
Thankyou for the confirmation on access part, I have raised the issue with the internal team . I would share their insights with you once I hear back from the team . Thanks
Hi @Victor Seifert ,
Kindly share below details :
We haven't gotten the same errors throughout the 5 days anymore. The pipelines run without a problem again - we haven't changed anything though... same as before when the errors occurred and same as it was before that when everything ran okay. I have no idea what the issue could be. I just hope it doesn't return :D
The Linkedservice was created around the 04th of September 2022.
The linked service is published.
Hi @Victor Seifert ,
Thankyou for sharing the update on issue. Glad to know you are not facing the issue anymore. I will convey the same to the team along with the details you provided. Please let us know if you face the issue again in any case. Thankyou .

We have the same issue. What was the fix?
There was no fix on our side. After a lengthy exchange with the support team of MS, they basically said that the latest round of patches on their side (while our communication was ongoing) should have fixed the issue. Since we didn't encounter the problem anymore for a couple of days in a row, I gave up trying to get more information out of them. Seems like they couldnt nail down what exactly was wrong themselves.
EDIT: we started seeing the errors again, so I guess MS didnt actually fix it...
