NO_WRITE_ACCESS_TO_OUTPUT

[harrisonford]

Hello!

When trying to run this example I get a weird "NO_WRITE_ACCESS_TO_OUTPUT: The provided data access role does not have write access to the output S3 URI" but I do have the roles needed.

When checking what goes in the API request I can see that:

"OutputDataConfig": { "S3Uri": "s3://comprehend-experiment-661346392611/train/output/661346392611-CLR-85826137aad9dca5c13352667268f0e0/output/output.tar.gz"

And this is super weird because to the train/output file it adds a weird middle file with my ID followed by CLR and a random code. Checking the value of S3 train output uri it should be correct:

train output = s3://comprehend-experiment-661346392611/train/output/

Do you know why this could happen?

Nevermind, it's a weird Role and policy issue in AWS. The FULL ACCESS policies don't give the exact policy you need for the Comprehend. Better to use UI once to make a classifier and check the exact Role you need.
