Iterate jpeg files from a folder and convert to base64

chafer — Sat, 16 Nov 2024 07:37:30 GMT

We are able to use the exchange module tBase64 to convert a 'single' image to base64 text. The conversion fails at tBase64 when we run it using the "tFileList" to iterate through multiple jpeg files (in this image below, we are using one image).

Has anyone found a solution that converts multiple jpeg images to base64 text files - with or without tBase64 module?

For the Job that fails:

tFileList mask is "*.jpg"

Using 'tFileInputRaw' to 'Read the file as a string'

Filename value: ((String)globalMap.get("tFileList_2_CURRENT_FILE"))

----------- Error ----------

Use tFileList_2_CURRENT_FILEPATH instead of tFileList_2_CURRENT_FILE
