base64ToBinary() disappearing after saving the Flow

[Nagaviswanath]

Hello Team,

I am getting base64ToBinary() disappeared after saving the flow. Is there any update on this bug yet? 

My formula: base64ToBinary(triggermultipartbody(0)['$content']) 

I am getting file content (string based) from HTTP request and my flow as follows:

My flow

The purpose of the base64ToBinary() is to convert unknown filetype(base64) to compatible file format in sharepoint(Binary)

This needs to be addressed as soon as possible and any other alternatives would be much appreciated.

Kind regards,

Naga

Hi @Nagaviswanath,

I have made a test on my side and the issue is confirmed on my side.the expression with base64ToBinary() disappeared after saving the flow.

However, even if the expression with base64ToBinary() disappeared after saving the flow, the flow would always run with expression base64ToBinary().

So don't pay attention to the expression displayed in the flow,you could run your flow to achieve your requirement even if the expression with base64ToBinary() disappeared.

Best regards,

Alice

Hello @v-yuazh-msft

I don't think the base64ToBinary() is working as sharepoint is not recognising file type of the files which were sent through HTTP request in Flow. Sharepoint is showing these files as Unknown file format, so i believe the function is not working.

Don't you think sharepoint recognises converted Binary files from Base64 if the base64ToBinary() is actually working as you said?

Kind regards,

Naga

I also get base64toString() disappearing - replaced with the dynamic content icon of the variable that is being processed, and i cannot re-edit the expression. It does appear to still be working but its really confusing to see.

FYI if I export this I can see it in the json:

"inputs": "\"@{variables('item_name')}\":  \"@{base64ToString(variables('item_content'))}\""

Hello @Nagaviswanath, did you found a solution for this problem ?

October 2019, still a feature of flow. 

I have found out that:

- The base64tostring/decodebase64 works if I save once and do not reopen the flow, ever. 

- If I encapsulate the method in something like trim(decodebase64(...)) or concat(decodebase64(...),'') the editor will not remove the method when reopening. 

Not a solution, but a workaround for plain/csv/xml files. I do not know about binary.

I have the same issue on the latest version of D365..

It is not resolving base64tobinary after saving the function disappears..

Is there a solution to this issue? 

Thanks...
