Hi all, i’m trying to manage my wf with some activities that returns about 1MB of datas. When datas are major than 1MB, i receive this Complete result exceeds size limit error, but if i remove some datas from my result and this datas are minor than 1MB all works fine. I read about [Find cause of "Complete result exceeds size limit" error](https://community.temporal.io/t/find-cause-of-complete-result-exceeds-size-limit-error/457) and i found the BlobSizeLimit that was setted to 2MB, but i don’t find how to configure it. Why i reached error when data is around 1MB? There is some particular reason for this? 2MB is perfect fit to my all scenarios. Thx a lot. A. ---

You can configure it your dynamicconfig via “limit.blobSize.error”. The value is an int (in bytes) with default value of 2097152 (2mb) - [temporal/constants.go at master · temporalio/temporal · GitHub](https://github.com/temporalio/temporal/blob/master/common/dynamicconfig/constants.go#L89) If the actual input argument size exceeds the warning size (limit.blobSize.warn set to 1/2 mb as default) you should get a warning message “Blob size exceeds limit”. This message is confusing and will do a PR to change it into something better. If it exceeds the max limit the invalid argument error should be "“Blob data size exceeds limit.”. Which one are you getting? ---

Thx @tihomir for the answer. Now it’s clear how to configure it. I can explain my use case that reached this kind of error. I’ve a lot of sequentially activities within my workflow. One of them return a 1.06MB size dto. I’m working with base configuration of blobSize. ![image](https://us1.discourse-cdn.com/flex016/uploads/temporal/original/2X/5/5e6d16c68d12de33425c3200a2d627c24a9bf2d9.jpeg). This is the error that i reached, but it’s quite strange because the limit is 2MB, correct? Then i tried to remove some entries and had 0.99MB size dto, all worked great. Can u explain me why i reach this error with base configuration? Thx a lot! A. ---

Yes the default is set to 2mb. Would you mind opening an issue here: [Issues · temporalio/temporal · GitHub](https://github.com/temporalio/temporal/issues) and describe the issue so server team can take a look? Make sure you put the server version in the issue. Thanks. ---

Also, at what point are you measuring the size of your input? Are you measuring it before its serialized and sent to server? If so I think that would not be an accurately represented measurement. The server checks the size limit of the serialized inputs. ---

Large payloads negatively affect service performance. So I would recommend storing your result in a blob store like S3 and passing the reference as an activity result. ---

@tihomir Neeraj this side from manish’s Team. we are getting below error. { “message”: “Complete result exceeds size limit.”, “source”: “”, “stackTrace”: “”, “cause”: null, “serverFailureInfo”: { “nonRetryable”: true } }
