  • 1.  VenturIQ-Azure Storage Utility - The input is not a valid Base-64

    Posted 03-25-2022 09:37
    Hi,

    I tried to use object "VenturIQ-Azure Storage Utility" action  "ListBlobItems" to get a list of items from my Blob containter. When I run action I get the below error message.

    Full error message: Internal : Could not execute code stage because exception thrown by code stage: The input is not a valid Base-64 string as it contains a non-base 64 character, more than two padding characters, or an illegal character among the padding characters. 

    Has anyone know how to handle this error?

    Kind regards

    Hi @Mateusz Wojcik,

    I dealt with a similar issue just the other day with some Base64-encoded data I was getting from GMail. What I found, in that case, is that the data contained '-' and '_' characters. According to RFC 4648, those are not valid characters for the main Base64 character set. However, when Base64 data is sent across the web the supported characters '+' and '/' cause issues because they are special characters in URLs. So, there's this concept of Base64 web safe characters which amounts to encoding data in Base64 and then replacing any '+' and '/' characters with '-' and '_', respectively.

    All that is to say you might want to check your Base64 data to see if it contains any '-' or '_' characters. If it does, replace them with '+' and '/' and then try to decode the data.

    Here's some example code:
    System.Text.StringBuilder _encodedData = new System.Text.StringBuilder(base64Data);
    _encodedData.Replace("-", "+");
    _encodedData.Replace("_", "/");

    If that doesn't work, I'd suggest reaching out to VenturIQ to see if they can offer some guidance. The support link they posted for that asset is https://venturiq.com/contact-us/

    Hi Eric,

    Thank you for response.
    I have made propose changes.
    It seems that characters "&", "=", and "%" are also invalid.
    Do you know how to replace them ?

    Kind regards

    @Mateusz Wojcik,

    Those are typical URL characters. Is your data part of a query string on a URL?

    Cheers,

    Ok, so those characters do encode, under Base64, to different characters. Are you encoding/decoding the credential yourself, or is it provided to you already encoded?

    Hi Eric, Thank you for your response. I do already have information of what I need. It is written in error message. I do not need to check it in config file. What I do not know is how to solve the problem. I connot find this version System.Memory.dll.

    Hi @Mateusz Wojcik,

    So you're getting an error about a missing DLL? Does the error tell you what version is expected?

    Cheers,
