Hi Dear Community, 

 

hope you are doing great,

 

Today I have noticed something weird in the flow where i am using below :

 

 

 

 

<img src="data&colon;image/jpeg;base64,{inserting content here}" alt="Image" />

 

End goal :- when an email arrived -> take email attachments and send it's content to mentioned email address.

 

error :- I am seeing unsupported format in the output flow run(Fig-1),  However once I resubmit the flow with old trigger it went well(Fig-2),

        Fig-1. Unsupported format on trigger

                Fig-2. after-resubmitting-the-flow

hoping to find solution for this,

 

Regards,
