base64 collection error

[langsem]

Hello i have a app that sends a collection of images to a web api. problem its that i have made a code that provides only the base64 value and in the power automate i use a for each to send each image with the http request. The error comes when the json collection suddenly decides to set a "," before the base64url at the two last images. Then it failes

Hi @langsem 

Since a Base64 value should never contain a comma, perhaps the easiest fix is to call the substitute function and to replace the comma with an empty string in your source collection.

make a regex function in power apps u mean to clean the string ? Wouldent it cause a conflicts if i have a collection with multiple base64 values ?
