File name issue with plus sign - Get blob content using path (V2)

Suresh Kumar Chermadurai 20

I am trying to get content of a file from Blob storage in Logic Apps using the connector "Get blob content using path (V2)". Connected Logic Apps with the specific Blob Storage using Managed Identity. Passing below blob path in the connector where file name having plus sign in it. Blob Path - /attachments/Testfile T&C+re+MISC+check+.pdf_IKE-256987.docx.

Output for the blob

{
  "status": 404,
  "message": "Specified resource /attachments/Testfile T&amp;C re MISC check .pdf_IKE-256987.docx/ not found.\r\nclientRequestId: 1b18d505-e570-4545-85a4-fba215783608",
  "error": {
    "message": "Specified resource /attachments/Testfile T&amp;C re MISC check .pdf_IKE-256987.docx/ not found."
  },
  "source": "xxxxxxxxxxxxxxxx"
}

All the plus sign are replaced with space and thrown file not found error. The file is available in the storage account container "attachments". Is this a limitation with the connector? If then what are all the characters will not work with the connector.

Hello Suresh Kumar Chermadurai,

Greetings! Welcome to Microsoft Q&A Platform.

Adding to above response, Since the blob name is URL-encoded in the backend, that is the reason why the '+' is replaced by ' '. Can you please try replacing the + with %2bor by modifying the file as per naming convention.

refer - https://learn.microsoft.com/en-us/rest/api/storageservices/naming-and-referencing-containers--blobs--and-metadata#unicode-characters-not-recommended-for-use-in-container-or-blob-names where it clearly mentions the blob naming conventions and rules.

Hope this answer helps! Please let us know if you have any further queries. I’m happy to assist you further.

Nehruji R - I’m trying to create a blob using the "Create blob (v2)" action by copying it from a source storage account where the blob name contains a '+' symbol. I attempted using '%2B' in place of '+', but the file was copied as empty and ended up in a Leased state. Any suggestions for this?

Looks like this is a limitation with the connector based on the below article.

https://learn.microsoft.com/en-us/connectors/azureblob/#known-issues-and-limitations

"The connector does not support blob names and paths that contain URL decodable characters, i.e. "+" or "%" followed by two hexadecimal digits."
