Conversion functions not working

I'm trying to use a conversion function and when I save the flow it gets removed.   It happens with any conversion functions but specifically I'm trying to use:

base64ToString(triggerBody()?['Signature'])

 

But when I save and then go back to the flow it ends  up being just:

triggerBody()?['Signature']

 

 (this is within a simple Initialize variable action)

 

What am I doing wrong?

Hi @FBaldwin,

 

Could you please share a screenshot of your flow's configuration?

 

Thanks for your feedback, the issue is confirmed on my side, but it doesn't happen with any conversion functions. My flow's configuration as below:3.JPG

Within Inputs field of Compose action, type the following formula:

base64ToString(body('Get_file_content')?['$content'])

 

But when I save and close my flow, then re-edit it, the flow shows up as below:4.JPGBut when I run my flow, the flow works successfully as below:5.JPG

 

 

I think the base64ToString() function has taken effect, this issue seems to be related to the display issue within Microsoft Flow. Please take a try to run your flow to check if the base64ToString() function has also taken effect on your side.

 

I would post this issue to my product team, if this issue is solved, I would reply here.

 

 

Best regards,

Kris

Anyhow my base64 has not taken effect.

Hi  @v-xida-msft,

 

I will try the approach share by you.

 

hi @FBaldwin

Hi @v-xida-msft,

 

I tested still have the same issue. The error message as below:-

 

BadGateway.

 

Error : The field 'documentbody' contains one or more invalid characters.

 

link to see the content of input : https://prod-30.southeastasia.logic.azure.com/workflows/f8fe1ca488964d3a8f1b248f05f922ab/runs/085867...

 

Currently i configure the flow to read from SQL database and convert the Varbinary type content data to Based64ToString to store the content of document to CRM you can see below screenshot of the flow:

Still not working for my side. Any alternative solution can share to me how to create annotation to CRM? when the data store in Client SQL is Varbinary type.

 

Regards,

Shee Hao

Yes the problem still exists

I don't think your error/issue is the same as mine.  I don't have a badFateway or anything and please note that if I copy and paste the Signature text into a tool like http://freeonlinetools24.com/base64-image   it decodes without issue

Hi @FBaldwin

 

Yes. I tested by using tool to convert my Varbinary data and copy paste to the Microsoft flow. No error occur and it works. So now i am not sure where is the problem occur. As i know from SDK CRM document content type will work if accept Based64ToString.

Shee Hao
