@janvit04 The pattern you need is this: ${input_date:toDate("MM/dd/yyyy hh:mm:ss"):format("yyyy-MM-dd HH:mm:ss")} I did this in a test which you can find here. In this example I have UpdateAttribute with an input attribute called input_date and its string value is "8/6/2023 12:46 am". In next UpdateAttribute i do the toDate and format. With this setup you may need to modify the format in toDate function to match your input string until it gets right format. For example I thought it should be m/d/yyyy but i got right output using MM/dd/yyyy.

Hi Steven, will do! I leave this topic open for a while in case anyone found a known issue for this combination CDP 7.1.8 + RHEL 8.8 Thanks

Hey Matt! I am truly grateful for your answer. You made me realize what I was doing wrong and I learned a lot while reading trough your explanation. I am going to revise the documentation again, as I am realizing that I did not had some concepts crystal clear before. Thanks again and I wish you a good day.

@sam_s0ni Apache NiFi never intended with the context of the NiFi framework to allow parameters to be dynamically accessed within NiFi Expression Language (NEL). The EvaluateElString() exposed a bug in which this was possible while never intended. That bug was addressed in apache NiFi 1.19 thus resulting in what you are seeing. As an alternative, you could store your schemas in an external database and pull those schemas back dynamically based on a FlowFile attribute instead of using Parameter contexts to store those schemas.

@ibrooks Excellent article here. I will definitely be using this in my CML Demos going foward. I just sent a PR w/ some flow improvements you may like to use as well.

@Sivaluxan Assuming Huawei OBS is s3 compliant( a quick search says it is), you should be able to use all of the S3/OBS based nifi processors. You would just need to satisfy the access/auth requirements in order to connect from NiFi to H OBS from within the of the processors below. https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-aws-nar/1.22.0/org.apache.nifi.processors.aws.s3.ListS3/index.html https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-aws-nar/1.22.0/org.apache.nifi.processors.aws.s3.FetchS3Object/index.html https://nifi.apache.org/docs/nifi-docs/components/org.apache.nifi/nifi-aws-nar/1.11.4/org.apache.nifi.processors.aws.s3.PutS3Object/index.html

@Aimen If you are still experiencing the issue, can you provide the information @steven-matison has requested? Thanks.

@Aimen I would be willing to help you get started. Shoot me a DM to co-ordinate a working session.

@steven-matisonthanks for you answer:) You can download a template here: download Instead of GenerateFlowFile, I have another processing section, but nevertheless, the relevant part starts with AttributesToJson going up until the PutBigQuery Processors 🙂
