OLE DB or ODBC error DataFormat error HRESULT 0x80040E4E

[h2bi]

Hello, all my tables have no errors in PowerQuery, i refreshed table by table all good, when i tried to load them into Power BI i started getting a weird error that i wasn't getting before in all the tables i am trying to load

Table1
    OLE DB or ODBC error: Exception from HRESULT: 0x80040E4E
    Unexpected exception
Table2
    Not enough arguments were passed to SEARCH function. The minimum number of 
    arguments for the function is 2. OLE DB or ODBC Error: Exception from 
    HRESULT: 0x80040E4E. Unexpected exception
Table3
    OLE DB or ODBC Error: Exception from HRESULT: 0x80040E4E. Unexpected 
    exception.
Table4
    OLE DB or ODBC Error: [DataFormat.Error] Cannot convert to numeric. Unexpected 
    exception.

Table4 i have made a step with the correct formats, there is no date column in the table and the column are all in text the correct format

The Table1 is the only one with date columns which are all in date format

My data sources are Sharepoint and Snowflake

What could be the solution? i tried everything i found on forums but nothing, could this problem coming from microsoft?

Hi @h2bi ,

As you can see from the code reporting the error,  here is my analysis of them in turn.

OLE DB or ODBC error: Exception from HRESULT: 0x80040E4E: it often relates to data type mismatches or encoding issues.

The solution is ensure that your data source’s character encoding matches the encoding expected by Power BI. Sometimes special characters (like cubic or degree signs) can cause issues. You can also clear cache or update Power BI.

Go to File > Options > Data Load > Clear Cache in Power BI Desktop
