Error when creating sensitivity label using multiple infotypes

Divya K Nair 41

While attempting to create a sensitivity label using a large number of sensitive info types, we received an error that said:

"The generated rule blob is too long. The maximum length is 49152 and the length of the rule blob is 86516."

How can we resolve this issue?

Hi @Divya K Nair ,

The error message you received indicates that the generated rule blob is too long. The maximum length allowed for the rule blob is 49152, but the length of the rule blob you generated is 86516, which exceeds the maximum length limit.

To resolve this issue, you can try to reduce the number of sensitive info types you are using in your sensitivity label. Alternatively, you can try to split your sensitivity label into multiple labels, each with a smaller number of sensitive info types.

Hope this will help.

Thanks,

Shweta

Hey @Shweta Mathur ,
The maximum length allowed for the rule blob is 49152 , Does Microsoft give us a little buffer cause where we tried saving the rule size was past the threshold and still i was able to save it but adding one more SIT Throws this error.
Thank you .
